Controlled air incinerator conversion to allow on-line waste additions

Incineration of low-level radioactive waste has been carried out by Ontario Hydro since 1977. The system is founded on a batch process type incinerator using a controlled air principle in which combustion air quantity in the primary chamber is controlled to 30-50% of stoichiometric. Demands on the incinerator have steadily increased as the generation of incinerable waste has outstripped the processing capabilities of the incinerator. A number of equipment modifications were implemented in an attempt to increase incinerator capacity. The latest and most significant modification involved installation of an on line loading system.
