【Abstract】 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 minimum 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 310.75MW, 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 96.71MW, 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.更多还原
