AP-90 Boiler Feedwater Heater ©PSX2010 AP-90 20101210 Application: Boiler Feedwater Heaters via Direct Steam Injection Power generating plants utilize steam boilers to produce electricity energy for their operation. These boilers often have feedwater heaters which are an integral part of the plant’s thermodynamic cycle. The presence of the heaters in the cycle improves the thermal efficiency of the power plant by lowering the amount of thermal energy required to generate a given amount of electrical by re-using produced steam in a heat exchanger to heat feedwater prior to the Deaerator (Fig. 1). Issues Associated with Boiler Feedwater Heating ! Heat exchangers are prone to mineral and scale build-up on the interna
