Specification:
In boilers, China wholesale boiler economizers are heat exchange devices that heat fluids, usually water, up to but not normally beyond the boiling point of that fluid. Economizers are so named because they 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. They 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).
Material compositionIt is made up of parallel serpentine tubes (carbon steel, alloy steel, etc.) and collection boxes and other supporting material composition. Tubes generally have 32, 38 and other types of specifications, according to user's needs separately.
Structural arrangement
Layout: vertical / horizontal.
Arrangement: alignments / staggered
