초록

Part of the synthesis gas produced by coal gasification in an allothermically heated fluidized bed reactor is burned after removal of dust and sulfur and serves as a source of energy to heat the reactor by indirect heat exchange and to produce the steam required for the gasification process. The flue gas exiting from the heat exchanger of the reactor can be used to perform work in expansion turbines. The rest of the synthesis gas is available for use in downstream processes, such as iron ore reduction, or can be burned and used to perform work in turbine...

Process for producing electricity from carbonaceous fuel comprising the steps of: supplying finely atomized carbon-containing fuel to a fluidized bed reactor; gasifying the fuel in the reactor by means of an essentially allothermal gasification reaction to produce synthesis gas; withdrawing the synthesis gas from said reactor; and purifying the synthesis gas so as to remove dust and sulfur from the synthesis gas; combusting a first portion of the purified synthesis gas and producing a first portion of flue gas; heating the reactor by indirect heat exchan...
