Carbon Steel Boiler Superheater Coil Thermal Coal Boiler Power Plant Waste to Energy

Functions and characteristics of superheaters

The Steam Superheater is a coil type heat exchanger which is used to produce superheated steam or to convert the wet steam to dry steam, generated by a boiler. It is different from a boiler in a way that, boiler utilizes both sensible heat as well as latent heat to convert water into steam while superheater utilizes only sensible heat to superheat the steam in order to increase its enthalpy.

Platen superheater

The platen superheater is composed of steel pipe with outer diameter of 32 ~ 42mm and header, which is generally suspended at the upper part of furnace or furnace outlet. The number of tubes in each screen is generally 15 ~ 30, which is determined according to the required steam flow rate.

Serpentine Superheater

The outside diameter of the pipe is generally 30-60mm. The convection superheater is the most commonly used, and the serpentine tube type is adopted. It has a relatively dense tube group, which is arranged in the flue of 450-1000 ℃ flue gas temperature, and is subject to the transverse and longitudinal erosion of flue gas. The flue gas mainly transfers heat to the pipe by convection, and some of it absorbs heat by radiation.

What are the differences of Superheater And Reheater?

Type	Advantages	Disadvantages	Supporting method
Pendant-type	1.Firm structural support	1. Flow blockage by condensed steam 2. Needs a 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.
