Stainless Steel Superheater And Reheater For Utility / Power Station , High Efficiency
Superheater is a part of boiler that further heats steam from saturated temperature to superheat temperature, also known as steam superheater.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.They are made up of a number of parallel pipes and an inlet and outlet header.
Most industrial boilers do not have superheaters, as many industrial processes and facilities require only saturated steam.Superheater is usually installed in power stations, locomotives and Marine boilers to improve the cycle thermal efficiency of the entire steam power plant.
Details
All the raw materials will be firstly made pipeline cutting.
It is consisted of a series of bare oil(carbon steel,alloy steel,or durable heat steel) and header and other auxiliaries. TubesΦ32,38,42 and so on,also as the request.

Differences
Type | Advantages | Disadvantages | Supporting method |
Pendant-type | 1.Firm structural support | 1. Flow blockage by condensed steam 2. Needs 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. |
Generally 30 ~ 60 mm.The most common type of flow superheater is
serpentine tube.It has a more intensive tube group, decorate in 450
~ 1000 ℃ flue of the flue gas temperature, flue gas of vertical and
lateral erosion.The flue gas mainly transfers the heat to the pipe
by convection, and some of the heat is absorbed by radiation.The
plate-type superheater consists of a plurality of tube screens,
arranged in the upper part of the furnace or at the outlet,
belonging to the radiation or semi-radiation type superheater.The
former absorbs radiant heat from the furnace flame, while the
latter also absorbs some convection heat.In power station boilers
above 10 mpa, both screen type and serpentine type superheater are
commonly used to increase heat absorption.The wall superheater
applied on the inner wall of the furnace is radiant superheater,
which is seldom used.The wall-mounted superheater is used in the
large capacity power station boiler to form the wall of the furnace
top and convection flue.The picture shows the arrangement of
several superheater.The small capacity industrial boilers with
superheater can meet the requirements only with single stage
superheater.
Application
Use for heating saturated steam, steam temperature could be up to
900 degree C.
