REGENERATIVE FEED WATER HEATING SYSTEM
REGENERATIVE FEED WATER HEATING SYSTEM In regenerative feed water system steam is bled from the turbine from various stages and is made to give up its latent or any super-heat to the condensate in a heat exchanger, this system is called regenerative system. What is Regenerative Feed Heating? A small portion of steam expanding through the turbine is bled off from different stages of turbine before reaching condenser and used to heat feed water in the feed water heaters. This is called regenerative feed heating system. Why Regenerative Feed water heating? Loss of work that could have been obtained by expanding the extracted steam in the turbine (because of if we expand more steam from the turbine then after doing work this steam condensed in the condenser due to which its losses latent heat after condensation). Reduction in the energy supplied in the boiler (reduction of coal required in boiler which release energy after burning) to raise the temperature and pressure of the fee
