Flue gas exit temperature
WebThe economizer is used to recover heat from the exit gas from the boiler to reduce the temperature of flue gas before venting into the atmosphere. The heat transfer is more effective if the economizer surface is large. The purpose of the evaporator is basically changing the phase of water from liquid to vapor, that is, evaporation. WebWe claim: 1.A method for humidifying air comprising the steps of: providing a water vapor laden flue gas having a first water vapor partial pressure and a first temperature from a combustion process to a first side of a first permselective water transport membrane; condensing at least a portion of said water vapor on said first side of said first …

http://pubs.sciepub.com/ces/1/4/2/index.html WebAug 12, 2016 · One of the key variables when designing a boiler is furnace exit gas temperature (FEGT). This is usually defined as the temperature in a vertical plane just in front of the convection pass as the flue gas escapes the radiant zone. This helps determine that the furnace heat absorption properly cools the flue gas before entering the …
WebQuestion: A 200-MW power plant has a 100 m stack with radius 2.5 m, flue gas exit velocity 13.5 m/s and gas exit temperature 145 °C with pressure of 2.02 Kpa.
