The change rule that coking yield and coke VCM increase as the cokingperiod shortens in the commercial delayed coking unit has been calculated by the model.
应用该模型计算出工业焦化装置成焦周期缩短后，焦炭收率和焦炭挥发分增加的变化规律；
2
As the excess capacity in a very long period of time will be normal, so coking industry is still very long winter.
由于产能过剩在很长的一段时期内将是常态，因此焦化行业的冬天还很长。

Coking furnace performance is critical to the safety and long period running of delayed coking unit.
