Title:

GASIFICATION MOTHER-CHILD BOILER FOR COKING, STEEL MAKING, CASTING AND POWER GENERATION

Document Type and Number:

WIPO Patent Application WO/2018/227949

Kind Code:

A1

Abstract:

A gasification mother-child boiler for coking, steel making, casting and power generation, the gasification mother-child boiler being formed by a combination of 6, 8, 10 or more sub-furnaces. A top portion of a sub-furnace is provided with a bellows, wherein a small electric motor is used to blow wind into the bellows by means of a pipe, and hot-air oxygen is transported from the bellows by means of a pipe into a furnace hearth that is closely connected to a water tank at a bottom portion of the sub-furnace, the hot-air oxygen being adjusted such that coal is completely scorched. The hot-air oxygen that is transported from the bellows reaches a second combustion chamber by means of a pipe, and gas that is generated by means of a gasification process in the furnace hearth is combusted in the second combustion chamber. The mother-child boiler changes a chimney that is originally configured in the air into heat-collecting pipes that are provided within each sub-furnace.
