Abstract
A pressurized coal gasification system having double wall containment vessels (2,10) is disclosed. The gasification vessel (2) is provided with a gas tight water seal (36) for connecting the lower end of the inner water-cooled vessel (4) with the bottom supported slag tank (32). The seal (36) prevents gas leakage between the vessel interior and the pressurized annular volume (24) formed between the inner and outer gasification chambers (4,6). A flow of clean, particulate-free product gas (60) is routed into the contiguous annular volume (24,26,28) formed between the inner water-cooled gas directing members (4,20,12) and the outer, pressure containing members (6,22,16) to prevent either leakage of raw product gas into the annular volume or dilution of the product gas (46) by leakage of the sealing gas (60) into the hot product gas flowstream.
