Steam/Hot Water Boiler Heating Element Bare Tube
Superheater/Reheater For Boiler
Production Of Superheater And Reheater
The superheater is a device used to convert saturated steam or wet steam into superheated steam or dry steam. The superheated steam is used in steam turbines for electricity generation and steam engines etc.
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 Superheater And Reheater
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.

ADVANTAGES Of Superheater And Reheater
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.
