Incinerators differ from the simpler methods of open burning as the operator has a greater level of control over the burning process. The resulting higher temperatures, longer holding times and greater turbulence lead to more complete combustion of the waste. Even though a wider range of wastes could 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 additional information proper waste management practices and also a list of what waste can and cannot be incinerated.

The incinerator manufacturer’s operating instructions must be followed at all times to guarantee designed temperature, holding time and turbulence conditions are achieved and to prevent damage to the facility. When operating during winter months, additional care must be taken because cold air introduced to the primary and secondary chambers can make it hard for ordinary operating temperatures to be done. Operators must be suitably 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 buying an incinerator.

The installation and operation of monitoring and control systems is critical for the proper and safe operation of any incinerator.  While the document is written for electricity 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 have to be monitored at all times using online instruments capable of measuring the combustion process and stack emissions quality. These instruments should be equipped with audible and visible alarms and be online whenever the incinerator is in operation, including’start-up’ and’cool down’ phases. Table 3 lists the monitoring and control system requirements.
