METHOD OF COOLING WITH CRUDE GAS OBTAINED BY A GASSIFICATION PROCESS

摘要

In this process, the hot raw gas is quenched with a part stream of the gas from which dust has not been removed and which is withdrawn at a temperature of between 200 and 800@C from the convection section of the waste-heat boiler system located downstream of the gasification reactor. The quench gas is in this case recycled by means of an injector into the quench zone located downstream of the gasification reactor.
