    High Efficiency Boiler In Thermal Power Plant , Power Plant Economiser Easy Operation


    Company Introduction

    Established in 1985, Zhangjiagang Hua Dong Boiler Co., Ltd. (trading as HD Boiler), is a
    professional industrial manufacturer, producing utility boiler,industrial boiler,HRSG boiler and all
    kinds of boiler parts, such as waterwall panels, economizers, air preheaters, superheaters,
    headers, spiral fin tubes, H-fin tubes, heat pipes etc.
    We are the qualified supplier for the following large boiler manufacturers in China:

    • Shanghai Boiler Works Ltd.
    • Hang Zhou Boiler Group Co. Ltd.
    • Harbin Boiler Co., Ltd.
    • Dong Fang Boiler Group Co., Ltd.
    • Wuxi Huaguang Industrial Boiler Co., Ltd.
    • Jiangxi Jianglian Energy & Environment Co., Ltd.
    • Dalian Boiler Works
    • Suzhou Hailu Heavy Industry Co., Ltd.




    Economizer is installed on the lower part of the boiler tail flue for recycling the waste heat of smoke, a device heating boiler feed water into steam drum pressure of saturated water heating surface, due to its high temperature flue gas heat, reduces the exhaust temperature of flue gas, save the energy, improve the efficiency, so called the Economizer.

    Steel tube economizer is not limited by pressure, can be used as a boiling type, generally from the outer diameter of 32 ~ 51 mm carbon steel tube.Fins and fins are sometimes added to the tube to improve heat transfer.The tubular economizer consists of horizontally arranged parallel elbow pipes (commonly known as serpentine pipes).

    Economizers are mainly used in industry, but also gradually spread to agriculture and some related industries on the commercial.


    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,

    Main technical advantages of our low temperature 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.

    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.
