Economizer Tubes CFB Boiler Economizer In Thermal Power Plant High Corrosion ASME
Introduction:
In boilers, Economical low installation costs better performance boiler economizer for CFB boiler are heat exchange devices that heat fluids, usually water, up to but not normally beyond theboiling point of that fluid.
Economical boiler economizers are so named because boiler economizers for water heating can make use of the enthalpy in fluid streams that are hot, but not hot enough to be used in a boiler, thereby recovering more useful enthalpy and improving the boiler's efficiency.
Better performance boiler economizers are a device fitted to a boiler which saves energy by using the exhaust gases from the boiler to preheat the cold water used to fill it (thefeed water).
