High pressure heater is used to heat boiler feed water by steam extraction of steam turbine to improve the thermal efficiency of the unit. It is arranged between the feed water pump and the boiler. The heated feed water pressure is as high as tens of MPa. It is the key equipment of thermal power generation unit.
Equipment Name: High Pressure Heater.
Installation form: vertical/horizontal.
Common materials of heat transfer tubes: SA556C2/20MnG/20/TP304.
Heat exchange area: 230~3500 square meters.
Usage: Power station boiler feed water heating.
Features: high commissioning rate, not easy to leak.
Matching units: 25MW~600MW.
The low-pressure heater is a shell-and-tube heat exchanger that uses the extraction steam of the steam turbine to heat the feed water to improve the thermal efficiency of the unit, and is arranged between the condensate pump and the deaerator.
