The Experimental Study On Coal-gasification In Double Circulating Fluidized Bed

Double circulating fluidized bed cold-test and double circulating fluidized bed coal gasification pilot preliminary thermal were tested, obtain the relevant operating parameters and operational experience To build double circulating fluidized bed cold and hot state test bed test bed to 0 ~ 0.6 mm sand as circulating fluidized bed material, to double circulating fluidized bed cold, a study of the pressure distribution on the impact of system operation, pressure on the feeder back to the impact of loop volume control system, and the optimum range of operating parameters, in order to double circulating fluidized bed thermal testing provide the basic data. To 0 ~ 1 mm Longkou coal particles as raw materials, using air as gasification agent, to double circulating fluidized bed coal gasification, thermal test, analysis of the typical course of the experiment failure, come up with solutions, and gas composition produced during the test and fly ash carbon content analysis.
