Product Description

Superheater
Fossil fuel power plants often have a superheater section in the steam generating furnace.The steam passes through drying equipment inside the steam drum on to the superheater, a set of tubes in the furnace. Here the steam picks up more energy from hot flue gases outside the tubing, and its temperature is now superheated above the saturation temperature.

Reheater
Power plant furnaces may have a reheater section containing tubes heated by hot flue gases outside the tubes. Exhaust steam from the high-pressure turbine is passed through these heated tubes to collect more energy before driving the intermediate and then low-pressure turbines.


In power station boilers, the effect of superheaters is to heat the steam to certain temperature for higher efficiency of the power station. Reheaters are steam superheaters to reheat the over-worked long-pressure or middle-pressure steam to certain temperature.


The use of rehearters can further improve heat power of the power station circulating and control the steam temperature of the end blades of the steam turbine within allowed range. Zigzag superheaters and reheaters of the Company are also unique with rigorous production technique, first-class production flow line and complete test methods.



Details


All the raw materials will be firstly made pipeline cutting.

It is consisted of a series of bare oil(carbon steel,alloy steel,or durable heat steel) and header and other auxiliaries. TubesΦ32,38,42 and so on,also as the request.


With the artistic apperance and accurate size,the advance process for bending tube and welding,the first rate test equipment and sophisticated technology




Differences

TypeAdvantagesDisadvantagesSupporting method
Pendant-type1.Firm structural support1. Flow blockage by condensed steam 2. Needs slow restart to purge the water that accumulates in the bottom.supported from above
Inverted-type1.Proper drainage of the condensed steam1. Lack the structural rigidity, especially in high speed gas flowSupported from below
Horizontal -type

1. Proper drainage

2. Good structural rigidity.

1. They do not view the flam directly so they are mainly from the convective typeUsually supported in the vertical gas ducts parallel to the main furnace.


Application


use for heating saturated steam, steam temperature could be up to 900 degree C.
Superheater Capacity Upgrades to Increase Power Generation

Workshop




Send us required technical data, such as steam capacity, presure, required temperature etc. We will design accordingly.
