摘要： A gasifier (10) having an associated boiler (26, 32, 42, 48), for converting coal to combustible gas, and also having a desulfurizer (20) downstream of the gasifier. In order to maintain the gas leaving the gasifier and flowing to the desulfurizer above a predetermined temperature, even when operating the unit at reduced loads, a temperature sensing device (56) continuously monitors the gas temperature upstream of the desulfurizer. If the temperature drops below a predetermined value, high temperature boiler water (62) is introduced to the economizer (26) rather than feed water (24), so that less heat is absorbed by the economizer from the gases under these conditions.

摘要： 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.

摘要： A steam generating diffuser comprising a plurality of heat exchange tubes arranged to form a horizontally disposed, longitudinally elongated open-ended divergent duct. A refractory lining is laid up around the inner surface of the divergent duct so as to protect the heat exchange tubes. The inlet of each heat exchange tube is connected to a lower water distribution header disposed beneath the duct and the outlet of each heat exchange tube is connected to an upper steam and water distribution header disposed above the duct. Each tube provides a fluid flow path between the lower and upper headers which is continuously upwardly directed.
