GASIFICATION AND SLAGGING COMBUSTION METHOD AND APPARATUS

摘要

The present invention relates to a gasification and slagging combustion method for gasifying combustibles, delivering produced gas and char (solid carbon) into a slagging combustion furnace, and combusting the gas and char at a high temperature and melting fly ash into molten slag in the slagging combustion furnace. The gasification and slagging combustion method includes gasifying combustibles in a gasification furnace (10) to produce a gas and a char, melting ash contained in the gas and the char in the slagging combustion furnace (11) while combusting the gas and the char at a temperature enough to melt the ash, discharging incombustibles through a discharge port from the gasification furnace and removing metals from the incombustibles discharged, crushing the incombustibles from which the metals are removed, and supplying the crushed incombustibles to the gasification furnace (10) or the slagging combustion furnace (11) or the duct.
