摘要

供热机组进行灵活性改造,对其热力特性进行试验研究.结果表明,在供热工况平均供热负荷为327.86 MW(1180.31GJ/h)时,最小出力平均电负荷为97.88 MW,为机组额定出力的29.66％,锅炉最低蒸发量为447.44 t/h,未投燃油助燃,燃烧稳定;最大出力平均电负荷为310.75 MW,为机组额定出力的94.17％,锅炉最大蒸发量为976.27 t/h.纯凝工况最小出力平均电负荷为96.71 MW,为机组额定出力的29.31％,锅炉最低蒸发量为304.44 t/h,未投燃油助燃,燃烧稳定;最大出力平均电负荷为332.87 MW,为机组额定出力的100.87％,锅炉最低蒸发量为962.70 t/h.主汽、再热汽温度、压力满足汽机运行的需要.

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 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.
