Title: Gasifying device for slag of coal
Inventor: TAKAMOTO NARUHITO
IPC: B29C53/08
Filed: 1983-12-29
Abstract: PURPOSE:To lower the temperature of a gasifying furnace, and to improve energy efficiency while effectively utilizing clinker formed by the gasifying furnace as a desulfuring agent by mixing limestone with coal and using the mixture as a raw material for the slag gasifying furnace. CONSTITUTION:A limestone supply pipe 12 is mounted to a gasifying furnace 1, and a piping system 11 supplying a desulfurizing tower 7 with clinker containing limestone from the gasifying furnace 1 is fitted. Coal in the gasifying furnace 1 is gasified, and ash in coal dissolves, and is changed into clinker together with CaO in limestone. Since an alkali component in ash increases and the viscosity of slag lowers by adding limestone to coal in the gasifying furnace 1, ash slag can be discharged smoothly even when the temperature of the gasifying furnace is lowered. Accordingly, the temperature of the gasifying furnace is lowered and the loss of sensible heat of a formed gas is reduced, and the energy efficiency of the whole gasifying furnace is improved while clinker produced in the gasifying furnace is utilized effectively as a desulfurizing agent.
