Product Information

Professinal supplier industrial steam iron boiler superheater for sale

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.

Superheater

In a subcritical boiler, the SH is between the main-steam header and the steam drum and consists of
• Saturated tubes that transport steam from the drum to the SH inlet header (when the SH tubes are not directly connected to the drum)

• Superheater banks with their respective inlet and outlet headers
• Attemperator station for STC
• Main-steam header with all fittings and terminating with the main-steam stop valve (MSSV)
Steam from the steam drum flows toward the main-steam header, and there should be no valve between the two to ensure flow in SH tubes under all conditions to prevent over­heating and failure.

Reheater

Reheating of steam involves withdrawal of partly expanded steam (at the end of the high — pressure cylinder of the turbine), taking it back to the boiler in cold reheat pipes, heating to the same or higher temperature as the superheated steam, and returning to the turbine in hot reheat pipes. In terms of hardware, an RH system comprises

• Cold reheat pipe from turbine to boiler
• Safety valves on the cold reheat pipe
• Emergency spray-water attemperator system on a cold reheat pipe or interconnect­ing pipe
• Reheater bank complete with inlet and outlet headers

• Hot reheat pipe from boiler to turbine

Construction

Immerse the serpentine tube in a liquid container.When the inside of the snake is liquid.In order to constantly fill the whole pipe, the liquid should be fed from the lower end of the pipe to the upper end of the pipe.When steam is introduced into the snake tube, in order to avoid water hammer and blockage due to the accumulation of cold liquid in the tube, steam should enter from the top and condensate is discharged from the bottom.

The structure of submerged coil heat exchanger can be divided into two types: undetachable and detachable.In the selection, should be based on the cleanliness of the medium and corrosion.Packing height and material used.The choice of gasket materials can be determined by the use of pressure, temperature and the nature of the medium in the equipment.

Function

Submerged coil heat exchanger, usually used for cooling, condensing or heating, cooling and evaporation of medium outside the tube.

Its advantages are simple structure, low cost and convenient operation and management.In addition, it can withstand high pressure in the coil. In addition, it is often used as the heat transfer component in the reactor with small heat transfer area.

Disadvantages: usually, the medium velocity in the container is very low, so the heat transfer coefficient outside the pipe is small.In addition, the overflow degree of all places in the container is roughly similar, so the average temperature difference is not large, so the heat transfer effect is poor.The equipment was bulky.Not suitable for use as a heat exchanger with large heat exchange area.

Material

The material of superheater&reheater is steel pipe,copper pipe,other nonferrous metal,ceremic pipe,graphite pipe and so on.
