Analysis of Abnormal IDF RB Function in 600MW Thermal Power Unit and Optimization of Control Strategy
The causes and treatment process of the abnormal operation of the induced draft fan(IDF)RB function of a 600MW thermal power unit is explained.Through analysis of the reasons for RB abnormality,which refers to the decrease of fuel control output to 0 t/h during RB period,and corresponding solutions were proposed to effectively improve the success rate and rationality of RB operation,thereby improving the operating efficiency of the unit.
