Abstract

PURPOSE: To make operation and control simple and economical and to make gasification of unburned part efficiently. by dust collecting using unburned part of fuel coal as granular.
CONSTITUTION: Crushed coal crushed by a crusher 4 is fed to a coal gasification furnace 5, and char (d) is separated from generated gas from the gasification furnace 5 by a char separator 6 such as a cyclone etc. The separated char is sent to a movable layer type dust collector. There, the gasified gas (c) is dust collected and sent to a burner from an outlet 11 side through a desulfurizer 14. The char sent to the dust collecting layer 13 from an inlet 8 is sent to the gasification furnace 5 together with crushed coal (b) which is gasification fuel, from an outlet 9 and utilized again as gasification fuel.
