Customizable High Temp Carbon Steel Superheater Coil ASME For Coal Biomass

How does a superheater coil work?

High-temperature flue gas or a heat source flows around or through the coil, transferring heat to the saturated steam inside, raising its temperature to a superheated state.
Product Description

The wall superheater is a special class of superheater. Sometimes part of the superheating surface needs to be located at the furnace proper. The wall superheater surface is used in these applications. A wall superheater is basically a flat panel of joined tubes that hangs either as close to the furnace membrane wall as possible or forms part of the furnace. Sometimes the backpass side walls form a superheating surface. Typically wall superheaters are the first superheater after the steam drum or the coolest superheater.



Specification

Functions

This superheater has two parts, the primary superheater and the secondary heater. The primary superheater is the first heater that is passed by steam after the steam comes out of the steam drum.

After the steam is heated on the super primary heater, eating steam will be passed on the secondary superheater to be heated again. So on the secondary superheater steam formed is the hottest steam among the others.

Steam from the secondary superheater which becomes superheated steam. SH steam will flow to rotate High-Pressure Turbine and then the pressure and temperature will drop.
