Steam Superheaters in Industrial Boilers coil type heat exchanger
ASME certification
Boiler Spare Parts Superheater Manufacturing
1. Our superheaters are manufactured according to the ASME
Regulations. DHB manufactures both coil type and shell type
superheaters depending upon the type of boiler and boiler capacity.
2. Coil type superheaters design generally consists of 180o coils
welded through the headers on both the sides. In a coil type
designs steam is inside the coil and flue gases are outside the
coil.
3. Shell type superheaters design generally used to superheat the
steam electrically using special heating elements stacked in a
shell and the steam flows over the heating elements.
Types of Superheater in Boiler
Depending upon the steam temperature requirement, Superheaters are
divided into two parts
1. Radiant Superheaters
Radiant superheaters are the type of superheaters that are
installed in a radiation zone just after the furnace. In
high-pressure boilers when the temperature difference in saturated
and superheated steam is around 100oC.Superheaters must be
installed in a radiant zone.
2. Convective Superheaters
Convective superheaters are installed after the convective bank of
tubes. When the temperature difference between saturated and
superheated steam is not more than 50oC. Superheaters must be
installed in a convective zone.
Steam Superheater in Boiler Manufacturer in DHB
1. Our boiler superheaters come with adequate safety features to
prolong the life of a superheater as well as your equipment where
the steam is used.
2. The safety valve is installed in a super-heater to prevent
operating pressure to exceed the design pressure of a superheater
in the boiler.
3. We manufacture steam superheaters that suit different type of
fuels such as:
- Solid Fuels (Wood, Rice Husk, Bagasse, Coal)
- Liquid and Gas fuels (Light and Heavy Oils, Natural Gas)
- Electrical operated steam boiler superheaters.
Benefits of Superheaters in Boilers
| 1 | Increase in efficiency of the steam power plant |
| 2 | Minimized erosion of turbine blade |
| 3 | Less steam consumption |
| 4 | Reduction of condensation loss in the boiler steam pipes |
| 5 | Increases the temperature of saturated steam by removing entrained
water particles from turbines steam |
