Why do coal

Why do coal-fired boiler power plants need to have low rear pass temperatures? This provision facilitates gradual drop of flue gas temperature as it passes from boiler's furnace(the highest temperature point/source) to chimney I am carrying out life cycle analysis of coal power plant for Indian condition Get price
