| Abstract: | Taking a 330 MW subcritical heat supply unit in northeast area of China as an example,the runback function hadn t been revised after its auxiliary apparatus reconstruction.The runback function of the feedair draft fan,the induced draft fan,the primary air fan and the feedwater pump need to be optimal designed.Through the experimental verification,the runback logic is reliable which can effectively guarantee the safety and the stability of the unit operation. |
