Feedback control strategy of longitudinal temperature and finished carbonization time for coke oven and its application

摘要

Based on the detailed analysis of the third coke oven in BaoSteel, a feedback control strategy of longitudinal temperature and finished carbonization time of coke ovens was proposed and it was applied to the third coke oven in BaoSteel. As a result, the ratio of the instance that the absolute deviation of the longitudinal temperature is within +- 7 deg C and the finished carbonization time within +- 10 min is more than 80 percent, having acquired the patent saving effect of an energy consumption lowered by 2.92 percent. At the same time, it can provide an example for the same coke ovens inside and outside the nation.
