KBW Koppers Babcock & Wilcox
KBW Koppers Babcock & Wilcox : A coal gasification process developed jointly by the Koppers Company and Babcock & Wilcox, intended to supply the synthetic fuels industry. The product is a mixture of carbon monoxide and hydrogen. Dry, powdered coal, oxygen, and steam are injected into the reactor. The reaction temperature is sufficiently high that the ash is molten; it runs down the reactor walls, is tapped out as a molten slag, and is quenched in water before disposal
