Incinerators differ from the simpler methods of burning as the operator has a higher level of control over the burning process. Even though a wider range of wastes may be destroyed using high temperature single or dual-chambered incinerators, determined efforts should nevertheless be taken to reduce the amount and type of waste generated and to implement other changes which would lead to reductions in air emissions. Refer to section 3 for further information proper waste management practices and a list of what waste can and can’t 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 center. When operating during winter months, additional care must be taken because cold air introduced to the primary and secondary chambers can make it difficult for normal operating temperatures to be achieved. 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 purchasing an incinerator.
The installation and operation of monitoring and management systems is vital for the safe and proper 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 electricity generation facilities, the principles apply equally well to other kinds of facilities and continuous emissions monitoring systems. For incinerators operating in Nunavut, key operational parameters have to 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 audible and visible alarms and be on-line whenever the incinerator is in operation, including’startup’ and’cool down’ phases. Table 3 lists the tracking and management system requirements.
