BLACK WATER FILTER FOR HIGH ASH CONTAINING FEEDSTOCK

摘要

The present invention involves the addition of a black water filter (30) to the outlet of the quench chamber (16) of the gasification reactor (12). The normal flow of water out of the gasification reactor (12) is through the side of the quench chamber (16), but in the present invention it leaves out the bottom of the quench chamber (16) into the black water filter (30). In the black water filter (30), slag in the black water is allowed to settle out. Soot water exits the top of the black filter (30) through outlet port (32) and flows to downstream purification/processing units.
