Industrial Economizer Coil Serpentine Tube for Boiler High Efficiency ASME Certificated

Application

The economizer can be matched with various industrial steam and hot water boilers. We made a technical transformation on fins of the economizer, which improved the heat transfer coefficient by 15%-30% and reduced the flue gas flow resistance by about 10%.

It is used in all modern plants. The use of economizer results in saving fuel consumption increases steaming rate and boiler efficiency.
Some of the common applications of economizer are given below, In steam power plants it captures the waste heat from boiler stack gases (flue gases) and transfers it to the boiler feed water. Air-side economizers HVAC (Heating, Ventilation, and Air Condition) can save energy in buildings by using cool outside air as a means of cooling the indoor space. Refrigeration: This is commonly used in industrial refrigeration where vapor compression refrigeration is essential. Systems with economizers aim to produce part of the refrigeration work at high pressures, a condition in which gas compressors are normally more efficient.

Descriptions

Economizers, or economisers, are mechanical devices intended to reduce energy consumption, or to perform useful function such as preheating a fluid. The term economizer is used for other purposes as well. Boiler, power plant, heating, Refrigeration, ventilating, and air conditioning (HVAC) uses are discussed in this article. In simple terms, an economizer is a heat exchanger.

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).

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 a result, the diameter and length under the same conditions, it has larger heat transfer area.
