Superheater&Reheater, Custom Component For Boiler
 

Superheater is a part of a boiler that heats the steam from the saturation temperature to the overheating temperature. It is also called a steam superheater.Superheater can be divided into convective type, radial type and semi-radial type according to heat transfer mode;According to the characteristics of the structure, it can be divided into serpentine pipe type, screen type, wall type and wall type.They are made up of parallel pipes and inlet and outlet manifold.

Most industrial boilers do not have superheaters because many industrial processes and living facilities require only saturated steam.In power stations, locomotives and Marine boilers, superheater is usually installed to improve the circulating thermal efficiency of the whole steam power plant.
 
 
Product Function&Features

HDB thermal efficient steam super heater for coal fired boilers
Specification:
Super heaters are the one of the most important boiler sapre parts that improves the thermal efficiency. High temperature steam boiler radiant super heater is usually applied in high pressure power plant boiler.
In the boiler, the role of super heater is to heat the saturated steam to a certain temperature of superheated steam to increase power plant efficiency. Repeater essentially further improves the thermal power plant cycle efficiency.
Steam Super heater Coils: Super heater coils are used in a boiler to generate saturated steam. The super heater coils are specially used in Boilers of Power plant. We manufacture Super heater coils in various grades of Alloy steel and in stain less steel tubes with or without support & Header as per customer's drawing.
 
Changes in boiler operating conditions, such as load level, fuel change, combustion condition change, etc., all have an impact on superheater outlet steam temperature, so in power station boilers there are means to adjust boiler outlet steam temperature to make it stable at the specified value.Commonly used means are:
(1) with water jet or surface type temperature reducer directly adjust the steam temperature;
(2) with the swing burner to change the temperature of the furnace outlet smoke;
(3) with smoke recirculation adjustment superheater heat absorption.When the boiler load increases, the temperature rise value of the inlet and outlet steam of the flow superheater increases, while the temperature rise value of the radiant superheater decreases.
 
If the convective superheater, radiant superheater and semi-radiant superheater are properly combined and configured, the outlet steam temperature can change less when the load and combustion conditions change.The heat absorption and steam flow rate of the parallel pipes in the superheater stack will be different in operation.In order to avoid excessive temperature in individual pipes, the superheater is divided into several pipe groups in large boilers. Steam of each pipe group is mixed with a collecting box outside the furnace and the steam guide pipe is used to make each pipe group transposition, so as to avoid excessive temperature difference between each pipe.
