SA213T22 alloy steel power station boiler superheater for biogas steam boiler boiler spare parts
Description
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.

| | 1.Firm structural support | 1. Flow blockage by condensed steam 2. Needs slow restart to purge the water that accumulates in the bottom. | |
| | 1.Proper drainage of the condensed steam | 1. Lack the structural rigidity, especially in high speed gas flow | |
| | 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. |

Function
Superheater is to increase the temperature of the steam above its saturation point.
Reheater is basically a superheater that superheats steam exiting the high-pressure stage of a turbine. The reheated steam is then sent to the low-pressure stage of the turbine. By reheating steam between high-pressure and low-pressure turbine it is possible to increase the electrical efficiency of the power plant cycle beyond 40%.The reheat cycle is used in large power boilers since it is feasible economically only in larger power plants.
Certification
Features
1. As the flue gas across tube, the flue gas side of the heat capacity of exile to strengthen, under the same heat transfer coefficient, wall temperature vertical preheater than ordinary steel increased 10-30 Degree Celsius, the overall heat transfer coefficient of about 20.3-24.2W;
2. Two horizontal sealing tube box, the sealed tube box structure welded high strength, pipe damaged or the overall change can only block, and heat-packing seal, can only replace the damaged pipe tube, easy maintenance.
3. The tube air preheater is mainly used for boiler preheater, the low temperature.
