Stainless / Carbon Steel Superheater Coils Processing High Efficeincy

Superheater

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

Product Information

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.
