Abstract
The utility model discloses a kind of promotion systems of coal gasification performance, including first pickling tank, second pickling tank, drying tank, mixing tank, first fixed reaction bed, second fixed reaction bed and and separating device;After the coarse coal of the utility model is processed by promotion system, the fly ash separated by separating device after the coarse coal gas generated can be returned to mixing tank by seventh pipeline as catalyst and coal powder mixed to continue subsequent reaction, improve the CO yield, effectively improve the coal gasification performance, improve the utilization efficiency of coal resources.Simultaneously, since the mass of fly ash particle is larger, the residence time of fly ash particle is longer after returning mixing tank, gas-solid contact time is longer, and the conversion rate of fly ash is higher.And in seventh pipeline, mechanical valve is not needed, so the operation time of pipeline can be prolonged.
