Incinerators differ from the simpler methods of open burning since the owner has a greater level of control over the burning process. The resulting higher temperatures, more holding times and greater turbulence lead to more complete combustion of the waste. Although a larger variety of wastes could be destroyed using high temperature single or dual-chambered incinerators, determined attempts should nevertheless be taken to decrease the quantity and type of waste generated and to implement other modifications which would result in reductions in air emissions. Refer to section 3 for additional information appropriate waste management practices and a list of what waste can and cannot be incinerated.
The incinerator manufacturer’s operating instructions should be followed in any way times to guarantee designed temperature, holding time and turbulence requirements are attained and to avoid harm to the facility. When operating during winter months, additional care must be taken because chilly air introduced into the primary and secondary chambers can make it hard for ordinary operating temperatures to be attained. Operators must be properly trained and qualified to operate the equipment under both normal and emergency conditions. Owners are strongly encouraged to consult with manufacturers or other qualified persons with expertise before buying an incinerator. Additional advice on the selection of incinerator technology and their operational requirements can be obtained by referring to Environment Canada’s Technical Document for Batch Waste Incineration.
The setup and operation of monitoring and control systems is essential for the proper and safe operation of any incinerator. The design, installation, certification and operation of continuous emissions monitoring systems (CEMS) must comply with the principles explained in Environment Canada’s Protocols and Performance Specifications for Continuous Monitoring of Gaseous Emissions from Thermal Power Generation. For incinerators operating in Nunavut, crucial operational parameters have to be monitored in any way times using on-line tools capable of measuring the combustion process and stack emissions caliber. These tools should be outfitted with visible and audible alarms and be on-line whenever the incinerator is in operation, including’startup’ and’cool down’ phases. Table 3 lists the tracking and control system requirements.
