The energy-saving results of these units can be further improved by widening the regulating range of the extraction pressure and by using tow-stageheating of district-heating return water.
扩大供热抽汽压力调节范围及采用热网回冰的两级加热,可进一步提高该型机组的节能效益。

A heatingstage allows the temperature of sublimation to be recorded.
在加热阶段可以记录下升华的温度。
