Open feedwater heater three inlet thermo
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… Web1 de jul. de 2014 · A model is introduced for the thermal analysis of closed feedwater heaters in which wet steam is extracted from the steam turbine (and piped into the …
