Abstract

This process features separate gasification and combustion on same moving grate (1). The grate can also be manufactured as a cascade (6). The device comprises of chamber with moving grate (1). Under this grate the air is injected (2). Above the grate the combustion chamber is separated into two parts (3.1 and 3.2) into which the air is injected (4). The fuel is additionally heated and gasified by passing hot flue gases, recirculation or steam injection (5) through the fuel. During gasification this does not introduce oyxgen so synthesis gas of higher energy value is obtained. Fuel inlet (7) is positioned higher allowing larger amount of fuel into the first part of the chamber (3.1) thus generating larger amounts of synthesis gas. The device is designed to allow exit of synthetics gas through the exhaust outlet (8) and further use of it or mixing with other final incineration flue gases in the final combustion chamber (10). Into the final combustion chamber the air (oxygen) is injected, for perfect combustion.
