CDQ (coke dry quenching system) is a waste heat recovery system that recovers waste heat from hot coke with circulating gas and that generates high-pressure steam. In heat recovery systems, it is very important to obtain maximum efficiency. However, the waste heat quantity fluctuates because of operational changes in the waste heat source process. Therefore, it is necessary to establish the operating method to obtain maximum efficiency under these fluctuating conditions. For this purpose, the dynamic model of CDQ is proposed, and the validity of this model is confirmed by comparing the calculation result with the operation data. Next, it is shown that there exists an optimum circulating gas flow rate in relation to the coke flow rate using this model. By adopting this optimum circulating gas flow rate, 1 [t/h] more high-pressure steam can be generated, compared with the former operation.
