SA213 TP312 Carbon Steel Low Temperature Steam Boiler Economizer

Self-design Carbon Steel Boiler Economizer Spare Parts for Evaporator Use

Economizer Information

ADVANTAGES
1. The economizer is to heat the boiler feedwater (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.

We can manufacture three types of boiler economizer, bare tube
economizer, H-finned tube economizer and spiral finned tube
economizer.

Boiler Economizer is the energy improving device that helps to
reduce the cost of operation by saving the fuel. The economizer in
Boiler tends to make the system more energy efficient. In boilers,
economizers are generally designed to exchange heat with the fluid,
generally water. The exhaust from the boilers is generally in the
temperature range of 200°C – 250°C, so there are a huge amount of
losses from the boiler if any heat recovery devices are not
installed after it. Boiler Economizer that suit your boiler system
and will increase its overall efficiency from 3% – 5%. Increase in
boiler efficiency will save a lot of your operating cost and
eventually will prolong the life of your boiler system.

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.
