Abstract:

The coal blend for stamping coke oven is pre-treated in the fluidized bed equipment with coke oven flue waste gas as heat source and power source. Production application shows that the functions of coal blend moisture control and classification of fluidized bed type coal moisture control technology are obvious, after moisture control the moisture of coal blend is lowered by 2.2%, 1 474×104m3 return gas consumption is reduced, 8 750t of CO2 discharge and treatment of 20 000t of coking waste water are reduced, the production capacity of coke oven is raised by 5% and dust content in discharged waste gas is less than 50mg/m3.
