Product Description

Product Description

ODM CS Steam Superheater Coils in Boiler Heat Exchanger Accessories
 Superheating raises overall efficiency as well as avoids too much condensation in last stages of turbine which avoids blade erosion.
• The heat of combustion gases from furnace is utilised for removal of moisture from steam and to superheat the steam.
• Super-heaters ususlly have several tube circuits in parallel with one or more return bends,connected between headers.
• Heat from the hot gases to the vapour in the surperheater is transferred at high temperatures.
• Therefore promary section of superheater is arranged in counterflow and secondary section in parallel flow to reduce the temp. stressing of the tube wall.

Difference

Type	Advantages	Disadvantages	Supporting method
Pendant-type	1.Firm structural support	1. Flow blockage by condensed steam      2. Needs slow restart to purge the water that accumulates in the bottom.	supported from above
Inverted-type	1.Proper drainage of the condensed steam	1. Lack the structural rigidity, especially in high speed gas flow.	Supported 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 type.	Usually supported in the vertical gas ducts parallel to the main furnace.

Our Advantages

Superheating system Superheater Coil

• Superheaters in large capacity boilers are of both convective and radiant type.
• The convective type superheaters are placed in the second pass of the boiler, and these are also called low temperature super heaters. Generally about a 40 to 60 degree centigrade temperature pick up takes place on the steam side in this superheater.
• The steam from this moves to a radiant type superheater called the panel or platen superheater, and about a 70 to 100 degree centigrade pickup take place there.
• This is followed by the final superheater, and the remaining required temperature is picked up here. One has to understand that the designer can vary the pickup pattern depending upon his way of practice or requirement.
• But in all the methods adopted, the final temperature must be within a narrow range generally plus / minus five degrees centigrade. The superheaters are so surfaced that, for the design fuel of the boiler, there will not be any desuperheating requirement.

 

Quality Control

1. Impact test and Strength calculation report with applied materials information.

2. 100%NDT(non-destructive inspection) report of steel plate, tube and electrode.

3. X-ray, γ-ray and liquid penetrant test inspection report (welding seam): to ensure the quality of the entire boiler.

4. Hydraulic test report: ensure the standard working pressure and safety.
