Excellent Heat Transfer Performance Of Steam Heaters
Aug 03, 2017

As a heating device, steam heater has been used in many aspects. Since it is different from the air heater, it is necessary for us to have a good look at what kind of heaters should be used in the present situation.

The steam heater is a steel-aluminum composite fin tube as heat exchanger, Steam (heat Exchanger) Electric Heater so it combines the pressure resistance of the steel tube and the high thermal conductivity of aluminum, heat transfer performance is excellent, and has a certain degree of anti-corrosion, and it is compact structure, easy to clean.

The specific characteristics of steam heaters are:

(1) The heat transfer element adopts the spiral fin, and the fin is a whole one-time pressing forming, so the connection of the base pipe is good, the contact heat resistance is small, Steam (heat Exchanger) Electric Heater and the heat transfer coefficient is high.

(2) It can maintain a constant low resistance in the range of large temperature variation, Steam (heat Exchanger) Electric Heater and has good resistance to temperature and vibration.

(3) The finned tube is the wrong column arrangement, so the heat transfer area is large and the heat transfer coefficient is high.

(4) The layout of piping is very reasonable, and the air fluidity is very uniform.

(5) The steam heater has been tested by water pressure before leaving the factory to ensure that no leakage occurs.

The installation and use of steam heaters is also an important part, Steam (heat Exchanger) Electric Heater it can not be ignored, specifically:

(1) Steam heaters should be inspected before use, mainly to see whether there is collision or damage, if there is damage, should be repaired, and need to be tested and tested again.

(2) The hoisting and installation should be carried out according to the stipulations, the hoisting should be smooth when lifting, in order to prevent the distortion of components, or to touch bad fins.

(3) After the steam heater is installed to clean up debris, Steam (heat Exchanger) Electric Heater including all places, in order to prevent the blockage of fins, Steam (heat Exchanger) Electric Heater the impact of normal operation.

(4) When the steam heater is not used, the internal water should be discharged cleanly so as to prevent the pipe from freezing and cracking in winter.

The steam heater uses the boiler steam as the heat source to heat the air, and its design is based on the condensation and exothermic process of steam, is to make superheated steam condensation heat into saturated steam, and then condensation heat into saturated water, heating steam on the spiral fin tube external cross-swept air produced a stable phase change exothermic process, releasing all the latent heat of vaporization, Steam (heat Exchanger) Electric Heater the air heated after condensation into saturated water discharge.

Using tubular cluster structure, the tube row composed of steel-aluminum composite spiral finned tube is composed of heat exchanger monolithic units, single or several heat exchanging single chip in parallel group, and the steam heater is formed in tandem. The series and parallel heat exchanger adopts the building block type assembly structure, which is small in size and compact in structure and convenient for maintenance and replacement.

The steam heater consists of shell, inlet manifold, hydrophobic joint box, tube bundle fixed plate, spiral finned tube bundle, hydrophobic water pipe and hydrophobic thermal expansion elbow, positioning casing, Duct transition section and duct flange.
