Abstract
A process is disclosed for controlling the combustion and temperature in an solid waste-to-steam incineration system comprising a grated combustion zone and a steam boiler. This control is achieved by a synergistic combination of oxygen enrichment of an air stream and liquid quench fed to the combustion zone. The disclosed process includes the steps of adjusting the amount of solid waste passing into the combustion zone in order to maintain a constant flow of steam leaving the steam boiler, adjusting the amount of liquid quench to the incinerator in order to maintain a constant temperature in the combustion zone and adjusting the amount of oxygen enrichment of the air stream in response to a change in flow of the liquid quench to the incinerator. An apparatus for accomplishing the foregoing is also disclosed.
