HRSG Boiler Superheater and Reheater Desuperheater system ASME Standard Chinese Manufacturer

Superheating system

• 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.

Desuperheating system

• Three major systems are adopted the world over: the injection type, the flue gas flow diverting type, and the burner tilt. The last two are adopted for reheater steam temperature control. The first one is adopted for superheater temperature control.
• It also used in reheaters during emergencies when there is a need to quench the temperature even after reaching the maximum of control on the normal system adopted.
• The material selection for the superheater before the injection will be greatly influenced by the quantity of injection.
