摘要

An apparatus for the removal of particulate matter from the gaseous product stream of an entrained flow coal gasifier includes an initial screen (28), an intermediate screen (16) which is aligned with the direction of flow of the gaseous product stream and a final screen (18) transversely disposed to the flow of gaseous product and which apparatus is capable of withstanding a pressure differential of at least 10 psi (70 kPa) at the temperatures of the gaseous product stream.
