2 super-heaters, economisers & air heaters.A superheater is a vital part of the a boiler system that is used to increase the overall efficiency of a thermal power plant.More specifically, it is a device which converts wet steam (saturated steam) into dry steam as dry steam contains more thermal energy.Fouling: fouling of economiser.
function of economiser in thermal power plant is to recover some of the heat from the heat carried away in the flue gases up the chimney and utilize for heating the feed water to the boiler.It is simply a heat ex-changer with hot flue gas on shell side and water on tube side with extended heating surface like fins or gills.
Chat Onlineeconomisers are commonly used as part of a heat recovery steam generator in a combined cycle power plant.In an hrsg, water passes through an economiser, then a boiler and then a superheater.The economiser also prevents flooding of the boiler with liquid water that is too cold to be boiled given the flow rates and design of the boiler.
