Modeling and feedforwad control of flue gas denitration in coking reversing process

There is a large amount of energy waste in coking flue gas desulfurization and denitrification integrated device during the revising process of coking, in order to solve this problem, aiming at the unique reversing process of coking, the reasons for the change of NOx concentration in this process are deeply analyzed; the disturbance of inlet and outlet NOx concentration during the reversing process is modeled by a proposed data driven identification method, the verification is carried out based on the actual data of two 55-hole and 6-meter top charging coke ovens, according to the statistical data, the relationship model of inlet and outlet NOx concentration loss is obtained; we designed a feedforward control system and the feed forward control rate of O 3 is calculated based on the outlet disturbance model, the power consumption cost savings is obtained through simulation, which indicates the necessity of the work in this paper.
