INDIRECT DUAL BUBBLE FLUIDIZED GASIFIER

摘要

Provided is an indirect dual bubble fluidized gasifier, comprising: a fuel storage unit which stores fuel; a fuel supply unit which comprises a screw feeder to transfer fuel from the fuel storage unit; a gasifier reaction unit which uses fuel supplied from the fuel supply unit to perform gasification reaction; and a combustion reaction unit which provides heat source required for the reaction in the gasifier reaction unit. The indirect dual bubble fluidized gasifier can be installed at low costs compared to a circulating fluidized bed reactor; can be manufactured easily as standardized products with a simplified shape, compared to a conventional indirect dual bubble fluidized gasifier; and can exhibit high gasification efficiency like a conventional indirect dual bubble fluidized gasifier, compared to a single bubble fluidized gasifier.;COPYRIGHT KIPO 2015
