    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 recuperative and conductive heat transfer system (10, 10′) that is operative to effect therewith the heating within the second portion (20, 20′) of the heat transfer system (10, 10′) of a “working fluid” flowing through the heat s transfer surfaces (32, 32′) as a consequence of the transfer thereto by conduction of heat from a multiplicity of regenerative solids (24, 24′). The multiplicity of regenerative solids (24, 24′) derive their heat from a recuperation thereby within the first portion (12, 12′) of the heat transfer system (10, 10′) from either an internally generated or an externally generated source of heat (22, 22′).

    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.
