ABSTRACT:
This invention relates to the combustion of metal-containing scrap rubber such as used tires in a combustion chamber equipped with a traveling-grate stoker without allowing binding of molten metal to the stoker for effective utilization of scrap rubber as a fuel for a boiler or the like. On the traveling-grate stoker of the combustion chamber, which travels from a rear part to a front part of the chamber, blocks of coal supplied from a coal feeding port in the front wall of the chamber is cast by a spreader into the chamber to form coal deposits in a substantially uniform thickness on the stoker for combustion. At the same time, scrap rubber is fed from a chute discharging into the combustion chamber through a side wall defining the chamber via a rotary valve built into the chute in adequate amounts and burned on the ash zone formed by already burned coal on the traveling-grate stoker.
