LP Feedwater Heater
The extraction steam from the steam turbine is used to heat the main condensate from the condensate pump, so as to raise the temperature of the feed water, reduce the amount of steam discharged from the steam turbine to the condenser, reduce the energy loss and improve the cycle efficiency of the thermal system.
There are three types of LP feedwater heaters, inverted vertical, vertical and horizontal. Vertical and horizontal heaters are normal types. The heating surface of the heater is generally composed of a straight bundle or a U-shaped bundle of brass or stainless steel tubes. The heated water enters the heater tube bundle from the water inlet, and the tube bundle absorbs the heat of the heated steam in the steam space of the heater, which is transferred to the flowing water in the tube from the tube wall, and the heated water flows out through the outlet of the heater. There are safety accessories including safety valve, pressure gauge, thermometer and liquid level gauge on the equipment to ensure the safe and efficient operation of the equipment.
