Incinerators differ from the simpler methods of open burning

Incinerators differ from the simpler methods of open burning as the operator has a higher degree of control over the burning process. The resulting higher temperatures, longer holding times and greater turbulence lead to more complete combustion of the waste. Although a wider range of wastes can be destroyed using high temperature single or dual-chambered incinerators, determined efforts should still be taken to reduce the quantity and type of waste generated and to implement other changes which would result in reductions in air emissions. Refer to section 3 for further information proper waste management practices and a listing of what waste can and cannot be incinerated.

The incinerator manufacturer’s operating instructions must be followed at all times to ensure designed temperature, holding time and turbulence conditions are achieved and to avoid damage to the facility. When operating during winter months, additional care must be taken because cold air introduced into the primary and secondary chambers may make it difficult for normal operating temperatures to be achieved. Operators must be properly trained and qualified to operate the equipment under both normal and emergency conditions. Owners are strongly encouraged to consult system manufacturers or other qualified persons with expertise before purchasing an incinerator. Additional guidance on the selection of incinerator technologies and their operational requirements can be obtained by referring to Environment Canada’s Technical Document for Batch Waste Incineration.

The installation and operation of monitoring and control systems is critical for the proper and safe operation of any incinerator.  The design, installation, certification and operation of continuous emissions monitoring systems (CEMS) should comply with the principles described in Environment Canada’s Protocols and Performance Specifications for Continuous Monitoring of Gaseous Emissions  from Thermal Power Generation. While the document is written for power generation facilities, the principles apply equally well to other types of facilities and continuous emissions monitoring systems. For incinerators operating in Nunavut, key operational parameters must be monitored at all times using on-line instruments capable of continuously measuring the combustion process and stack emissions quality. These instruments should be equipped with visible and audible alarms and be on-line whenever the incinerator is in operation, including ‘start-up’ and ‘cool down’ phases. Table 3 lists the monitoring and control system requirements.

APPENDIX 2 – MODIFIED BURN BARREL DESIGN AND SPECIFICATIONS

A modified burn barrel is typically constructed from a 45 gallon metal fuel or oil drum. The modifications result in greater

heat generation and retention, better mixing of the waste with incoming air and longer holding time inside the barrel.

Together, these modifications result in more complete combustion of the solid waste than does open burning on the ground or

in a pit.

Environmental Guideline for the Burning and Incineration of Solid Waste

People living and working in Nunavut often have limited options available for cost effective and environmentally sound

management of household and other solid waste. The widespread presence of permafrost, lack of adequate cover material and

remote locations make open burning and incineration a common and widespread practice to reduce the volume of solid waste and

make it less of an attractant to wildlife.  A wide variety of combustion methods are used ranging from open burning on the

ground to high temperature dual-chamber commercial incinerators.  Generally, high temperature incinerators are more expensive

to purchase and operate and cause less pollution than do the less expensive and lower temperature methods.  However, high

temperature incinerators can safely dispose of a wider variety of waste than can the lower temperature open burning methods.

The Guideline for the Burning and Incineration of Solid Waste (the Guideline) is not intended to promote or endorse the

burning and incineration of solid waste. It is intended to be a resource for traditional, field and commercial camp

operators, communities and others considering burning and incineration as an element of their solid waste management program.

It examines waste burning and incineration methods that are used in Nunavut, their hazards and risks and outlines best

management practices that can reduce impacts on the environment, reduce human-wildlife interactions and ensure worker and

public health and safety. This Guideline does not address incineration of biomedical waste, hazardous waste and sewage

sludge. The management of these wastes requires specific equipment, operational controls and training that are beyond the

scope of the current document.

The Environmental Protection Act enables the Government of Nunavut to implement measures to preserve, protect and enhance the

quality of the environment. Section 2.2 of the Act provides the Minister with authority to develop, coordinate, and

administer the Guideline.

The Guideline is not an official statement of the law. For further information and guidance, the owner or person in charge,

management or control of a solid waste is encouraged to review all applicable legislation and consult the Department of

Environment, other regulatory agencies or qualified persons with expertise in the management of solid waste.

Waste Burning and Incineration Combustion Process

The combustion, or burning, of solid waste proceeds through a series of stages. Water is first driven from the unburned waste by heat produced from material burning nearby or from an auxiliary burner. As the waste heats up, carbon and other substances are released and converted into burnable gases. This is referred to as gasification. These gases are then able to mix with oxygen. If the temperature inside the burn chamber is high enough and maintained for a long enough period of time, the hot gases are completely converted into water vapour and carbon dioxide, which is then released into the air. If the temperature inside the burn chamber is not high enough and the burn time is too short, complete conversion of the burnable gases does not occur and visible smoke is released into the air.  Another result of burning at low temperatures is the creation of pollutants that were not originally present in the waste. This process is known as de novo synthesis. Dioxins, furans and other complex chemical pollutants can be formed through this process.

Ash produced from combustion takes the form of either fly ash or bottom ash.  Fly ash is the fine particles carried away in the form of smoke while bottom ash is the course non-combustible and unburned material that remains after the burn is complete. The type and amount of pollutants in the fly and bottom ash depend upon what waste is burned and completeness of the combustion process.

The completeness of combustion is determined by all of the following factors:

Temperature

The temperature generated is a function of the heating value of the waste and auxiliary fuel, incinerator or burn unit design, air supply and combustion control.  Complete combustion requires high temperatures. Generally, temperatures that exceed 650oC with a holding time of 1-2 seconds will cause complete combustion of most food and other common household waste.  Segregation of waste is required when using methods that don’t routinely achieve these temperatures. Dual chamber incinerators, which are designed to burn complex mixtures of waste, hazardous waste and biomedical waste, must provide a temperature higher than 1000oC and a holding time of at least one second to ensure complete combustion and minimize dioxin and furan emissions.  When these high temperatures and holding times are achieved, waste will be completely burned and ash, smoke and pollutant concentrations will be minimized.

Because exhaust gas temperatures vary from ambient to greater than 1000°C each time a batch waste incinerator is used, optional air pollution control systems with evaporative cooling towers and scrubbers are seldom recommended. However, it may be necessary to employ these systems with large continuous feed incinerators if additional cleaning of exhaust gas is required by regulatory authorities.

Holding Time

Complete combustion takes time.  Holding time, otherwise known as retention or residence time, is the length of time available to ensure the complete mixing of air and fuel, and thus the complete burning of waste. Low temperatures, low heating values of the waste and reduced turbulence require that the holding time be increased to complete the combustion process.

Turbulence

The turbulent mixing of burnable gases with sufficient oxygen is needed to promote good contact between the burning waste and incoming air. This will help in achieving the high temperatures at which waste can be completely burned. The amount of mixing is influenced by the shape and size of the burn chamber and how the air is injected. Passive under-fire ventilation achieved during open burning does not result in sufficient turbulence for the burning of a wide variety of waste.  Also, it is important not to overfill the burn chamber as airflow may be blocked and the amount of turbulence further reduced.  The more advanced incineration designs provide effective turbulence through the forced introduction of air directly into hot zones.

Composition of the Waste

The heating value, wetness and chemical properties of the waste affect the combustion process and the pollutants that are contained in the resulting smoke and ash. The higher the burn temperature, holding time and turbulence that are achieved, the less effect the composition of the waste has on completeness of the burn.

Burning and Incineration Methods

The burning and incineration method used is a major factor in determining what type of waste can be safely and effectively disposed of. The methods commonly used in Nunavut include open burning on the ground, unmodified burn barrels and various mechanical incineration systems.  Other useful methods include the use of burn boxes and modified burn barrels. Each method is discussed separately in the following sections.

2.1.1    Open Burning

Open burning means the burning of waste where limited or no control of the combustion process can be exercised by the operator. This method includes burning solid waste directly on the open ground or in burn boxes or burn barrels and often does not achieve the temperatures or holding time needed for complete combustion of the waste to occur.  This results in the formation of potentially hazardous pollutants and ash, which are likely to impact nearby land and water. Food waste that is not completely burned through open burning can also be a powerful attractant for animals.

The various open burning methods can also present a risk of uncontrolled vegetation and tundra fires through the release of hot sparks or embers. The level of fire risk depends upon the type of open burning used, its location, the skill of the operator and the environmental conditions that exist at the time (i.e. dryness of the surrounding vegetation, wind).

The open burning of solid waste remains a common practice in Nunavut.  It is the policy of the Department of Environment to eliminate or minimize open burning of mixed solid waste to the extent practicable and to encourage more acceptable methods of disposal and incineration.

Open Burning on the Ground

Open burning on the ground involves burning solid waste that has been piled directly on the surface of the ground or placed in a small open pit. Many large and small communities and camp operators in Nunavut continue to practice open burning on the ground as a
means of reducing the

volume of solid waste that must ultimately be disposed of. In general,

open burning on the ground results in the incomplete combustion of waste and the release of various
harmful pollutants to the air, can cause vegetation or tundra fires through the uncontrolled release of hot sparks and embers, and is actively discouraged by the Nunavut Department of Environment as a method for disposing of unsegregated or mixed solid waste.

Burn Boxes

There are two basic types of burn boxes. The enclosed burn box is constructed using heavy sheets of steel or other metal while the open burn box is constructed using expanded metal grating. The latter type is commonly referred to as a burn cage. These devices are not commercially-available in Nunavut, but can be constructed using locally available materials. For example, the enclosed metal burn box shown in Figure 2 is made from a dump truck bed and steel plating.

Burn boxes are considered a modification of open burning. Combustion air is provided passively using a natural draft making electricity unnecessary. Burn boxes are single chambered units.  Waste is raised off the bottom of the box by placing it on grates inside the unit. Unburned bottom ash falls through the grate during burning making removal easier once a sufficient amount has accumulated. Combustion air in enclosed burn boxes is typically provided by cutting holes near the bottom of the box allowing for better mixing with the burning waste.

Open burn boxes, or burn cages, are an improvement over enclosed burn boxes as the waste is exposed to natural drafts through the metal grating on all surfaces including the bottom. This enables air to better mix with burning waste and promotes more efficient combustion throughout the burning period.
Both types of burn boxes are
constructed with hinged tops to enable easier loading and cleaning.

Unlike open burning on the ground, burn boxes help to contain the burning waste within a specific location reducing the risk of fire spreading to other disposal areas or surrounding tundra, while still enabling moderate amounts of solid waste to be burned.

Burn Barrels

There are two basic types of burn barrels – the unmodified burn barrel and modified burn barrel.

Figure 3 – Open Metal Burn Box

The unmodified burn barrel is normally a 45 gallon, or 205 litre, metal fuel or oil drum with the top removed. These devices typically operate at a low temperature resulting in incomplete combustion of the waste and production of large volumes of smoke and fly ash.

A modified burn barrel is a 45 gallon metal fuel or oil drum that has been affixed with devices or features which result in higher burn temperatures, better mixing of the air and a longer holding time. These modifications include a ‘metal mesh basket’ insert or grate designed to suspend the burning waste.
Evenly spaced vents or holes cut above the bottom of the barrel supply combustion air. These features provide for enhanced passive under-fire ventilation and promote better contact between the waste being burned and incoming air. The basket insert is topped with a hinged lid and a chimney port for attachment of an exhaust pipe or stack. The lid helps to increase heat retention and holding time inside the barrel while also allowing for easier loading and mixing of the  waste. The removable mesh basket enables access to the unburned bottom ash.

Modified burn barrels can be built using commonly available materials. They can either be pre-built locally or transported to the site for assembly. Detailed construction plans are provided in Appendix 2.

Although modified burn barrels are designed to create an advantage over open burning on the ground, burn boxes and unmodified burn barrels through achieving higher burn temperatures and increased turbulence and holding time, incomplete combustion of waste and the release of  pollutants to the atmosphere are still likely. In fact, emissions testing by Environment Canada on a modified burn barrel in April 2011 suggest that these devices do not provide any improvement over open burning on the ground in terms of

Figure 4 – Modified Burn Barrel

emissions quality, particularly if wet food waste is added to the waste mixture. Other common  problems include easily overfilling the unit and loading waste that should not be burned (refer to section 3.2).  Wet or frozen masses of waste are particularly difficult to burn and the resulting partly burned food waste may still attract animals. The proper operation of modified burn barrels is critical to achieving the most efficient burn possible. Basic operating instructions are provided in section 4.1.

Burn barrels are capable of burning only small volumes of solid waste. Like burn boxes, they reduce the risk of fire spreading to vegetation and tundra by containing the burning waste to a specific location.

Made-in-Vietnam waste incinerator shows its power

Made-in-Vietnam waste incinerator shows its power

VietNamNet Bridge – The waste incinerator of Vietnamese inventor Trinh Dinh Nang has been used in Bac Kan, Tuyen Quang and Thanh Hoa. But if it is used in other provinces as well, and therefore, can be produced on a large scale, the production costs will be much lower.

Nang’s waste incinerator was displayed at the Vietnam 2015 International Equipment and Technology Trade Fair, which caught the attention from many visitors.

He began working on such an incinerator some years ago, encouraged by the idea that his incinerator may help reduce the negative impact caused by hundreds of tons of medical waste.

In 2009, after successfully creating an incinerator, he filed a patent registration for his ‘hazardous waste incinerator’ to the Ministry of Science and Technology and got the patent in 2012.

Nang’s incinerator is a system which comprises a comprehensive combustion chamber which can burn waste in an uninterrupted process. The incinerator utilizes nano technology which disintegrates hazardous smoke, dust and frog.

The product is believed to have outstanding features which allow it to operate more effectively than products of the same kind.

Nang said that his waste incineration system is movable. The system can work properly if users have a small water tank and can treat the water.

He also said that all the incinerators available in Vietnam don’t have the pressure balance like his. The incinerator can burn waste, eject fire and not oil into burning materials. In the center of the combustion chamber, the temperature can reach 1,800oC.

With Nang’s incinerator, it doesn’t take much time to burn waste. The oil is durable, and there is no technical trouble with oil tubes.

The Ministry of Science and Technology (MST) has certified that Nang’s incinerator is the first medical waste incinerator in Vietnam which can satisfy the Ministry of Natural Resources and the Environment’s standards and it consumes the volume of fuel 80 percent lower than import products.

If the incinerator runs with diesel, it will need VND5,000 only to burn one kilo or waste. Meanwhile, the incinerators from US, Japan and UK would consume VND70,000-80,000 worth of fuel to burn a kilo of waste.

The outstanding feature of the made-in-Vietnam incinerator is that it can treat many kinds of waste, including domestic garbage and medical waste.

Director of the Bac Kan Science and Technology Department Do Tuan Khiem said the incinerator is a suitable choice for localities with moderate waste capacity. The machine is highly efficient and fuel-saving, which is big advantage in Vietnam’s conditions.

Animal waste management plant inaugurated in Marsa

The new plant would help in reducing energy losses in the incineration process as well as reducing harmful emissions

Wasteserv inaugurated a €12 million animal waste management in Marsa earlier today.

Speaking at the inauguration of the new Wateserv EU-funded autoclave rendering plant for the treatment of animal waste, Wasteserv CEO Tonio Montebello said that the project was part of its drive to improve the country’s waste treatment infrastructure.

Montebello also explained that the plant would result in substantial savings made in the incineration plant, which processes some 6,000 tonnes of waste a year.

Projects manager Jean Luke Zarb said that the problem with the current system was that a lot of energy was being wasted in incinerating water or fats on the carcasses.

“This plant will work essentially as an industrial pressure cooker in that it will dry up the carcasses beforehand,” he said, adding that this would ultimately result in less energy required by the incinerator.

He added that the fats would also be used as fuel for the plant itself, therefore reducing its fuel consumption.

Stressing that the plant would also be used to treat materials coming from Gozo, Montebello said that the new plant would also banish issues that normally rose when the incinerator was under maintenance, ensuring a seamless transition and operation.

Environment minister Leo Brincat said that the drop in fuel consumption would also ultimately lead to less harmful greenhouse gas emissions.

“Another novelty the plant will introduce, is in expired foodstuffs containing animal by products, which would normally have to be incinerated,” he said using a pizza with meat as an example.

“The plant will allow us to treat these foods and then forward them to other treatments plants to turn them into biofuels,” he added.

Brincat said that the project would also increase Wasteserv’s overall operation, and that the company was also looking forward to the inauguration of the Malta North MBT in the coming months.

EU funds parliamentary secretary Ian Borg added that the project, 85% of which was funded by the EU, was also completed in record time – about a year.

“The government is also currently evaluating projects for the latest €200 million fund package under the European Regional Development Fund,” he said.
