    摘要: A slag discharge system includes a slag bath at a bottom portion of a gasifier; a slag cooling water circulation line that discharges a mixture of slag and a slag cooling water from the slag bath; a coarse slag separator device that separates coarse slag contained in the slag cooling water; a fine slag separator device connected to the coarse slag separator device downstream side, the fine slag separator device separating fine slag; and a circulator pump connected to the fine slag separator device downstream side, the circulator pump creating a water flow in the slag cooling water circulation line; wherein the fine slag separator device includes a branch section where the slag cooling water circulation line branches into a plurality of branch lines and again joins together as one line, a fine slag filter portion, and a shutoff valve and disposed in each of the plurality of branch lines.

    摘要: A system is disclosed provided with: a slag bath that retains slag cooling water and receives slag; a slag cooling water feed line and a slag pump outlet via which the slag and the slag cooling water are pumped and fed to a slag separation device; a circulation pump that forms a water flow for pumping out the slag; a slag cooling water circulation line linking from the slag separation device to the slag bath; a reverse flow line that causes the slag cooling water dispensed from the circulation pump to flow in reverse in the slag cooling water feed line; a selective supply unit capable of selectively supplying the slag cooling water dispensed from the circulation pump to the slag cooling water circulation line and the reverse flow line; and a water supply line, one end of which is connected to the slag cooling water feed line.
