ExperimentalStudy on Thermal Characteristics of Thermal Power Unit Flexibility Technical Reform
The thermal characteristics of the heating unit were tested and modified flexibly.Under the heating condition,the results showed that the average heating load was 327.86MW(1180.31GJ/h),the average electric load of the mini-mum output was 97.88MW,which was 29.66%of the rated output of the unit,and the minimum evaporation capacity of the boiler was 447.44t/h without fuel,combustion stability.The average electric load of the maximum output is 310.75 MW,which is 94.17%of the rated output of the unit,and the maximum evaporation of the boiler is 976.27t/h.In the pure condensing condition,the average electric load of the minimum output under pure coagulation condition is 96.71 MW,which is 29.31%of the rated output of the unit.The minimum evaporation of the boiler is 304.44t/h,and the combustion is stable without fuel injection.The average electric load of the maximum output is 332.87MW,which is 100.87%of the rated output of the unit,and the minimum evaporation capacity of the boiler is 962.70t/h.Main steam and reheat steam temperature and pressure meet the needs of steam engine operation.
