摘要: 福建三钢 140 t/h 干熄焦装置实际处理能力达不到设计能力,干熄炉操作困难,不能满足配套焦炉的正 常产能要求。干熄炉运行过程中存在循环供风量小、锅炉入口阻力大、排焦温度高、容易浮焦等问题。分析原 因为干熄炉斜道的有效通风面积偏小和风帽尺寸不合理。提出了改造干熄炉斜道区通风面积的解决措施,有效 提升了干熄炉处理能力,满足了配套焦炉正常生产。

关键词: 干熄焦, 斜道区, 通风面积

Abstract: The existing capacity of 140 t/h CDQ unit of Fujian San Steel can not reach the designed capacity.The operation of CDQ chamber is difficult,and fails to meet the production requirement of coke ovens.Some problems also exist,including insufficient circulating air volume,high resistance at boiler inlet,high temperature of coke charging and floating coke.Through analysis,it is found that air ventilation area of CDQ connecting duct is not large enough and dimension of cowl is not reasonable. And this paper also provides solutions for modifying the ventilation area of the connecting duct,which helps to improve the capacity of CDQ unit and guarantees normal coke oven production.

Key words: CDQ, Connecting duct, Air ventilation area
