摘要： In a retrofit system for hot solids combustion and gasification, a chemical looping system includes an endothermic reducer reactor 12 having at least one materials inlet 22 for introducing carbonaceous fuel and CaCO3 therein and a CaS/gas outlet 26. A first CaS inlet 40 and a first CaSO4 inlet 64 are also defined by the reducer reactor 12. An oxidizer reactor 14 is provided and includes an air inlet 68, a CaSO4/gas outlet 46, a second CaS inlet 44, and a second CaSO4 inlet 66. A first separator 30 is in fluid communication with the CaS/gas outlet 26 and includes a product gas and a CaS/gas outlet 32 and 34 from which CaS is introduced into said first and second CaS inlets. A second separator 50 is in fluid communication with the CaSO4/gas outlet 46 and has an outlet 52 for discharging gas therefrom, and a CaSO4 outlet from which CaSO4 is introduced into the first and second CaSO4 inlets 62, 66. The chemical looping system is in fluid communication with at least a portion of an existing power generation system.

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.
