Customized Designed Boiler In Thermal Power Plant , Power Plant Economizer Carbon Steel
Main technical advantages of economizer
1. The equipment body can be designed into many modules to ensure the long term and stable running;
2. The low temperature economizer manufactured by our company can guarantee the wall temperature is 5-10 ℃ higher than the acid , and flue outlet temperature is 10-15 ℃ higher than the wall surface temperature
3. Wall surface temperature can be adjusted according to the boiler load and fuel changer to avoid corrosion under low temperature
4. Changer the DCS system of the existing boiler to achieve the auto and remote control by computer.

Economizer is a mechanical device intended to reduce energy consumption, or to perform another useful function like preheating a fluid. The economizer is used for other purposes as well boiler, powerplant, and heating, ventilating, and air-conditionin(HVAC) uses are discussed in this article.In simple terms, an economizer is a heat exchanger.
Steam boiler economizer can be made of alloy steel, carbon steel or other kind of material as per the customer’s requirements. It conforms to the standard of ASTM, EN, DIN, GB. The manufacturing equipment is 30~185MN hydraulic press, the forging ratio >3,
1. The economizer is to heat the boiler feed water (softened water) to raise the feed water temperature, instead of heating the boiler water.Absorbing the waste heat of flue gas to heat the boiler, reducing the heat loss, improving the efficiency of the boiler and saving coal accordingly.
2. The economizer shall install the safety valve and temperature gauge separately. In case of water shortage accident of the boiler, the bypass waterway of the economizer shall be opened immediately and the inlet and outlet of the economizer shall be closed.
3. The feed water is heated in the economizer before entering the evaporative heating surface to reduce the heat absorption of water in the evaporative heating surface, which is equivalent to replacing part of the evaporative heating surface with the economizer.
4. The heating surface of the economizer is much cheaper than that of the evaporating heating surface.
