摘要:

利用焦炉烟道废气为热源及动力源,在流化床设备内对捣固焦炉配合煤进行预处理。生产应用表明,流化床煤调湿技术对配合煤调湿及分级作用明显,调湿后配煤水分降低2.2%,减少回炉煤气用量1 474×104m3,CO2减排8 750t,减少焦化废水处理量2万t,焦炉生产能力提高5%,排空废气粉尘含量<50mg/m3。

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.
