ABSTRACT:
A coincineration process whereby sewage sludge or other toxic liquid chemical waste is incinerated with a supplemental fuel such as municipal refuse, coal, sawdust, tire chips and the like involves introducing the sewage sludge into the incineration zone by means of a pressure spray nozzle or a spinning cone or disc atomizer. In the form of ultrafine solids, liquid or gas, a supplemental fuel may be introduced with the sewage sludge. Supplemental fuel may also be introduced into the incinerator by conventional means. Addition of tire chips in the feed provides in a higher incineration zone temperature and significantly reduces dioxin compounds present in the incineration zone off gas. Also, to reduce the scaling and fouling of the boiler tubes and incinerator, to increase the density and pumpability of the sewage sludge, and to eliminate metal salt deposits from the incinerator, the boiler feedwater and the sewage sludge are each contacted with an electromagnetic field device prior to heating.
