Product Description
Stainless steel export to Covanta Energy company electrostatic precipitator HRSG recoverying system
Product Description
1.In boiler,economizers are heat exchange devices that heat fluids,usually water,up to but not normally beyond the boiling point of that fluid.
2.Economizer are so named because they can make use of the enthalpy in fluid streams that are hot,but not enough to be used in a boiler,thereby recovering more useful enthalpy and improving the boiler's efficiency.
3.They are a device fitted to a boiler which saves energy by using the exhaust gases from the boler to preheat the cold water used the fill it(the feed water)
Technical specifications
1.Material Structure
Consists of a serious of spiral fin tubes, the headers of inlet and outlet, bend, frame and other auxiliaries.
2.Structure Arrangement
In line / staggered arrangement.
Characteristics
1.This type of economizer can largely develop the heat exchanging area than the bare economizer to add the heat transfer area, reduce the volume, compact structure and reduce the number of elbow and welding to make less leakage and add the heat transfer efficiency.
2.Not easy to collect dust and the fume pass through the fin tube to form the boundary layer to occur the vortex to make less chance for the fly ash particle to touch the tube wall.
3.Widely temperature range, high pressure limit.
4.Durable strong impact, reliable operation.
5.less fume resistance, reduced abrasion and long working life.
6.Beautiful appearance, simple fabrication process.
7.Diverse layout.
8·Ease of installation, ease of construction.
9·A wide range of working pressure .
Vapor-Compression Refrigeration
1.Another use of the term occurs in industrial refrigeration,specifically vapor-compression refrigeration.
2.Normally,the economizer concept is applied when a particular design or feature on the refrigeration cycle,allows a reduction either in the amount of energy used from the power grid;in the size of the components used to produce refrigeration,or both.
3.For example,for a walk-in freezer that is kept at -20ºF(-29ºC),the main refrigeration components would include;an evaporator coil,fans to blow air over the coil and around the box,an air-cooled condensing unit sited outdoors,and valves and piping.
4.The condensing unit would include a compressor and a coil and fans to exchange heat with the ambient air.

High Pressure Power Boiler Heating Surface Membrane Wall Argon Arc Welding For Biomass Boiler
High Pressure Power Boiler Heating Surface Membrane Wall Argon Arc Welding For Biomass Boiler Product Introduction Water wall panels with pins usually laid vertically on the inner wall of the furnace wall, it is mainly used to absorb the radiant heat emitted by the flame and high-temperature flue gas in the furnace.It is the main type of evaporating heating surface of all kinds of modern boilers and the basic component of boiler water circulation loop.Because of both cooling
High Frequency Welding H Fin Tube Economizer For Power Plant Boiler ASME
High Frequency Welding H Fin Tube Economizer For Power Plant Boiler ASME Product Description The boiler economizer is a device used to recover waste heat in industrial boilers, usually located at the tail of the flue of the boiler, which increases the feed water temperature and reduces fuel consumption by absorbing the heat of the flue gas, so as to achieve the effect of energy saving and emission reduction. But at the same time, as an environmental protection equipment, the
Carbon Steel SA192 Superheater Coil Argon Arc Welding 100% PT
Product Description: A boiler superheater is an essential component in a boiler system, responsible for increasing the temperature of steam produced by the boiler.

Boiler Industrial SA210A1 Steel Boiler Economizer Heat Exchange Part ASME Certification
Boiler Industrial SA210A1 Steel Boiler Economizer Heat Exchange Part ASME Certification Introduction The H-shaped finned tube is also known as the H-shaped fin tube, also known as the butterfly fin tube. It is to weld symmetrically two pieces of steel with an arc in the middle to form fins (ribs or butterflies), the frontal shape of which resembles the letter "H", so it is called the H-shaped finned tube. The two fins of the H-shaped fin tube are rectangular and approximately
