Boiler Economiser: Economiser Definition, Function

WebThe economizer, superheater and reheaters penetrate these walls; the penetrations are designed to be gas-tight. At the point of penetration, the side-to-side expansion follows saturation temperature. However, the header that forms the inlet or outlet of the component expands with the temperature of the steam or water that it contains. WebThe superheater is a device which recovers heat from flue exhaust gases of boiler which are thrown out of the system Function of Superheater To superheat steam coming out of boiler. To improve the efficiency steam power plant. WebEconomizers are commonly used as part of a heat recovery steam generator (HRSG) in a combined cycle power plant. In an HRSG, water passes through an economizer, then a boiler and then a superheater. The economizer 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. atleta da marinha
