PURPOSE:To make a char feed device of exclusive use unnecessary, and to improve combustibility and reactivity, by collecting formed char in a formed gas, storing it in a normal-pressure storage hopper, blending the char with pulverized coal to be fed to a gasifying furnace, feeding the blend to the furnace. CONSTITUTION:Pulverized coal and air are fed to the gasifying furnace 15, a mixture of formed gas and char is exhausted from the furnace 15, the char is separated by the char collector 16 such as cyclone, etc. set on the way to the formed gas line E, collected, and the gas is exhausted to the downstream side. After the collected char stored in the pressure collective hopper 17, stored periodically through the rock valve 18 in the normal-pressure char storage hopper 19, each fixed amount of the char is fed by the rotary valve 20 to the pulverized coal hopper 11, processed into a mixture of the pulverized coal and char, and fed through the rock valve 12, the weighing hopper 13, an the feeder 14 to the gasifying furnace 15. |
