Chemical Engineering Basics What is the effect on the performance of the economiser in the thermal power plant boiler, if the feed water temperature is very low due to preheaters being out for repairs or starving of steam supply ? Heat transfer efficiency of economiser increases due to picking up high heat from the flue gases Scale formation rate on economiser tubes increases Economiser tube life increases due to handling of low temperature water It results in corrosion due to the condensation on the flue gas side of the economiser tubes due to handling of low temperature water Heat transfer efficiency of economiser increases due to picking up high heat from the flue gases Scale formation rate on economiser tubes increases Economiser tube life increases due to handling of low temperature water It results in corrosion due to the condensation on the flue gas side of the economiser tubes due to handling of low temperature water ANSWER DOWNLOAD EXAMIANS APP
