Thermodynamic analysis of a combined reheat

The power cycle uses one open and one closed water heater (CWH) for purpose of feed water heating. A parametric analysis is performed to investigate the effects of boiler pressure, fuel flow rate, VARS evaporator cooling load and operating temperatures on performance of the topping power cycle and bottoming VARS.

2003-10-30·(steam). One could simply say that a boiler is as a heat exchanger between fire and water. The boiler is the part of a steam power plant process that produces the steam and thus provides the heat. The steam or hot water under pressure can then be used for transferring the heat to a process that consumes the heat in the steam and turns it into work.
