Economizer function, advantages, disadvantages, location, types

Economizer Function of economizer: The economizer is a heat exchanger used to preheat the feed water using the hot gases leaving the boiler. When the combustion gases leave the boiler after giving most of their heat to evaporator tubes, Superheater tubes and reheater tubes, they still possess lot of heat which if not recovered by … Read more

Function of Reheater

Q1. What is function of reheater in steam power plant? Reheater function Function of reheater: The function of the re-heaters is to re-superheat the partly expanded steam from the turbine. This is done so that the steam remains dry as far as possible through the last stage of the turbine. The reheater is generally located … Read more

Superheater, function, advantages, disadvantages, classification

Superheater Functions of superheater: The function of superheater in the thermal power plant is to remove the last traces of moisture from the saturated steam coming out of boiler and to increase its temperature sufficiently above saturation temperature as per requirement at inlet of steam turbine. The steam produced in the boiler is nearly saturated. … Read more
