China Hot Sale Customized Boiler Economizer

Specification:
Economizer is aheat exchanger device that captures the "lost or waste heat" from the boiler's hot stack gas. The latest technology boiler spiral finned tubes economizer typically transfers this waste heat to the boiler's feed-water or return water circuit, but it can also be used to heat domestic water or other process fluids
Our enconomizer is squeezing by high frequency welding method and the technology of steel strip according to certain structure automatically, continuous spiral welding outside the light tube wall, and then the other reserved part light tube bending, combination according to the requirement. As aresult, the diameter and length under the same conditions, it has larger heat transfer area.
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 aboiler, thereby recovering more useful enthalpy and improving the boiler's efficiency. Better performance boiler economizers are adevice fitted to aboiler which saves energy by using the exhaust gases from the boiler to preheat the cold water used to fill it (thefeed water).

2.Generally speaking, the height of the fin <=1/2d
3 The spiral finned tubes produced by our company are manufactured according to the principle:JB/T6512-92 DG1020-97Accessory:
The boiler economizer acts as awaste heat recovery device, ensuring that this heat does not go unused.
Instead, the heat is used to essentially preheat the water, so that less heat is required to bring the water to atemperature high enough to make steam
boiler parts Heat exchanger HFin tube economizer used in utility boilers, industrial boilers, marine power, such as the tail of heat exchanger components.
