Open feedwater heater three inlet thermo
WebOpen Feedwater Heaters The ideal regenerative Rankine cycle with an open feedwater heater. An open (or direct-contact) feedwater heater is basically a mixing chamber, where the steam extracted from the turbine mixes with the feedwater exiting the pump. Ideally, the mixture leaves the heater as a saturated liquid at the heater pressure. Webe) Consider the above reheat steam power plant operating under the condition that the bleed inlet to the Closed Feedwater Heater has been shut off at station (2), thus station (8) is at the same temperature as station (7) (60°C), and …

Detailed Design Specifications. Web10-60 A steam power plant that operates on an ideal regenera tive Rankine cycle with a closed feedwater heater is considered. The temperature of the steam at the inlet of the closed feedwater heater, the mass flow rate of the steam extracted from the turbine for the closed feedwater heater, the net power output, and the thermal efficiency are to be
The energy used to heat the feedwater is usually derived from steam extracted between the stages of the steam turbine. Therefore, the steam that would be used to perform expansion work in the turbine (and therefore generate power) is not utilized for that purpose. The percentage of the total cycle steam mass flow used for the feedwater heater is termed the extraction fraction and must be carefully optimized for maximum power plant thermal efficiency since increasing this frac… Web10-52A steam power plant operates on an ideal regenerative Rankine cycle with two open feedwater heaters.
