Steel Boiler Spare Parts Superheater Product Description

1. Superheaters are the one of the most important parts of boiler that improve the heat exchange efficiency.

2. In boiler, the role of superheater is to heat saturated steam to a certain temperature of superheated steam to improve power plant efficiency.In essence, the repeater improves the recycling efficiency of thermal power plant.

3. Superheater is the temperature of the steam above its saturation point.

Superheater Details

1. Generally 30 ~ 60 mm.The most common type of flow superheater is serpentine tube.It has a more intensive tube group, decorate in 450 ~ 1000 ℃ flue of the flue gas temperature, flue gas of vertical and lateral erosion.

2. The flue gas mainly transfers the heat to the pipe by convection, and some of the heat is absorbed by radiation.The plate-type superheater consists of a plurality of tube screens, arranged in the upper part of the furnace or at the outlet, belonging to the radiation or semi-radiation type superheater.

3. The former absorbs radiant heat from the furnace flame, while the latter also absorbs some convection heat.In power station boilers above 10 mpa, both screen type and serpentine type superheater are commonly used to increase heat absorption.

4. The wall superheater applied on the inner wall of the furnace is radiant superheater, which is seldom used.The wall-mounted superheater is used in the large capacity power station boiler to form the wall of the furnace top and convection flue.The picture shows the arrangement of several superheater.The small capacity industrial boilers with superheater can meet the requirements only with single stage superheater.
