ABSTRACT:
A refuse disposal system is disclosed including a combustion chamber, means disposed in the combustion chamber for supporting refuse to be burned, means for charging refuse on the support means, overfire means for supplying an increasing flow of combustion air above the support means as the temperature of the gaseous products of combustion increases above a first predetermined temperature, underfire means for supplying a decreasing flow of combustion air under the support means as the temperature of the gaseous products of combustion increases above the first predetermined temperature, override means for overriding the underfire means to decrease the flow of air under the support means when the temperature of the products of combustion decreases below a second lower predetermined temperature and means for reducing the rate with which the charging means places refuse on the support means when the temperature of the gaseous products of combustion increases above the first predetermined temperature.
