ABSTRACT:
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 turbines to produce electric current. The result is a process that is environmentally safer and operates with a better yield than direct coal burning or autothermal coal gasification, but requires no outside source of energy, such as nuclear power, as prior art allothermal coal gasification processes do.
