Superheater&Reheater, Custom Component For Boiler
Superheater is a heating surface that heats saturated water vapor under certain pressure into superheated water vapor under corresponding pressure.The heat absorption and steam flow of each parallel tube in the superheater tube group are different during operation.Boiler superheater is energy recovery boiler flue gas, the boiler steam heating can be obtained, a dry steam, to improve the boiler thermal efficiency, but also to steam turbines to avoid water hammer regenerator from steam turbine in the spent steam recycling energy, heat into the boiler circulating water and regenerator, level can be high pressure discharge of steam reheat, recovery boiler energy of these devices are large boiler steam system of auxiliary heating device, is beneficial to improve the energy efficiency of the boiler system, only the superheater and reheater is recycled flue gas energy, regenerator is recycling steam energy.The superheater can be divided into convection type, radiation type and half radiation type according to the heat transfer mode.According to the structural features can be divided into serpentine tube type, screen type, wall type and package wall type.Superheater tube wall metal bears the highest temperature in the pressure parts of the boiler. Therefore, high quality low carbon steel and various kinds of chromium-molybdenum alloy steel must be adopted. Sometimes austenite chromium-nickel stainless steel is used in the highest temperature part.
Super heater types:
1. Radiant super heater: it is the earliest type of super heater and it is located above or behind banks of water tubes to protection them from direct flam or fire.
Parameters that increases the convection
a. Increasing the fuel-and air flow (combustion gas flow)
b. Increasing the mass flow rate of the steam
Radiation is mainly dependent on the flam temperature. as the steam flow rate increases the exit temperature become lower.
Radiant super heater
They are placed exposed to the heat source whcih requires the improvement of metal temperatures.
Radiant and convetive super heaters and reheaters are used for high temperature steam.
The accessory of high temperature radiant steam super heater in boiler
It is made up of snake-like tubes (carbon steel, alloy steel or heat-resistant steel, etc.) and collection boxes and other supporting material. Tubes generally have φ32, φ38, φ42 or other types of specifications, according to user's needs separately.
Reheaters
They are the sane as the super heaters but as their exit temperature is a little bit less than super heaters and their pressure is 20% -25% less than the super heater, they can stand less quality material alloys.
Application:
Steam super heater is consisted of dense tube coils and is placed in the flue under the tempearture 450ºC-1000ºC.
For power plant boiler capacity over 10Mpa, platen and coiled superheater are usually adopted.
Details
| 1 | Material composition | Carbon steel, alloy steel or heat-resistant steel, collection boxes and other supporting material. Tubes are customized types of specifications. |
| 2 | Design pattern | Vertical or horizontal layout. |
| 3 | Advantages | Beautiful appearance, size, accuracy, first-class bending and welding technology, first-class detection equipment. |
Design structure
Send us required technical data, such as steam capacity, presure, required temperature etc. We will design accordingly.
