Detailed description of the feed pump
At this point, 0.9Mpa decompression to 0.2Mpa throttle pressure loss, there is a significant energy loss.
However, due to various reasons, the steam turbine pumping pressure does not match, in a considerable number of thermal power plants, often encountered in the heating pumping 0.9Mpa, 300 ℃ as a heat source, the valve decompression to 0.1 ~ 0.2Mpa, and then sent to
General small and medium thermal power plant deaerator using atmospheric, 0.12Mpa pressure, heating out the water temperature of 104 ℃.
General small and medium thermal power plant deaerator using atmospheric, 0.12Mpa pressure, heating out the water temperature of 104 ℃.
To this end, 0.9Mpa 300 ℃ heating extraction steam into the back pressure small steam turbine, so that drag the feed pump, exhaust gas 0.1Mpa into the deaerator to feed water.
