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 ? It results in corrosion due to the condensation on the flue gas side of the economiser tubes due to handling of low temperature water Economiser tube life increases due to handling of low temperature water Scale formation rate on economiser tubes increases Heat transfer efficiency of economiser increases due to picking up high heat from the flue gases It results in corrosion due to the condensation on the flue gas side of the economiser tubes due to handling of low temperature water Economiser tube life increases due to handling of low temperature water Scale formation rate on economiser tubes increases Heat transfer efficiency of economiser increases due to picking up high heat from the flue gases ANSWER DOWNLOAD EXAMIANS APP
