| 摘 要： | 目前双背压汽轮机是按单背压汽轮机来进行热耗率计算的，由此带来热耗率计算的偏差。原因是受低背压的影响，排汽损失增大，汽轮机2个不同背压的算术平均值对应的热耗率并不等于汽轮机2个不同背压对应的热耗率。提出双背压汽轮机热耗率较为准确的加权计算方法，以某电厂为例进行分析，并对双背压汽轮机的热力试验方法提出建议。

| Abstract: | At present heat rate calculate of the double back pressure turbine is according to single back pressure turbine,which brings deviation of heat rate calculate.Because of larger exhaust loss is in the lower back pressure,the heat rate mean in the lower back pressure and higher back pressure is higher than the heat rate in the single back pressure turbine.Therefore weighted average of heat rate is put forward.Taking a certain power plant for analysis,comments on heat rate test method for double back pressure t... |
