Power Plant 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).
Classicafition:
We can manufacture three types of boiler economizer, bare tube
economizer, H finned tube economizer and spiral finned tube
economizer. H-finned tube economizer is high efficient heat
exchanger economizer which is consisted of H-finned tubes.
Compared with bare tube economizer, H-finned tube economizer can
enlarge the heat exchange area and reduce the number of tubes. It
also can increase the flue gas flow area in order to reduce the
flue gas flow speed and abrasion.
H-finned tube can be made as double H finned tubes , with high
rigidness to fit long tube row.
The spiral finned economizer is a newly designed heat transfer
equipment, consists of spiral fin tubes to overcome the serious
abrasion and short service time.
