Steam Heaters Have Excellent Heat Transfer Performance
Aug 25, 2017

Steam heater is a fixed shell and tube heater, is widely used in the PTA device, its main feature is to increase the corrosion resistance of the protective material, at the same time with high corrosion resistance, light weight, plastic and other characteristics.

Steam heater as a heating device, now in a number of areas have been a lot of applications. Because it is different from the air heater, so today we need to come to a good study in order to know what kind of heater should be used where the analysis is described below.

Steam heater is made of steel and aluminum composite finned tube as a heat exchanger, so it combines the steel pipe pressure and aluminum high thermal conductivity, Steam (heat Exchanger) Electric Heater excellent heat transfer performance, and has a certain degree of corrosion resistance, and it is compact, Easy to clean.

Steam heater specific features are:

(1) The heat transfer element uses the spiral fins, and the fins are integrally pressed once, Steam (heat Exchanger) Electric Heater so the connection with the base pipe is good, the contact resistance is small, and the heat transfer coefficient is high.

(2) It maintains a constant low resistance value over a wide range of temperatures and has good resistance to temperature and vibration.

(3) finned tube is wrong layout, so the heat transfer area, Steam (heat Exchanger) Electric Heater heat transfer coefficient is also high.

(4) pipe design distribution is very reasonable, and the air flow is very uniform.

(5) steam heater in the factory has been hydrostatic test to ensure that no leakage phenomenon.

Steam heater installation is also an important part, can not be ignored, the specific are:

(1) steam heater should be used before the inspection, Steam (heat Exchanger) Electric Heater mainly to see whether the collision or injury, if damaged, should be repaired, and the need for re-testing and testing.

(2) should be carried out according to the provisions of lifting and installation, lifting lifting to be smooth, to prevent distortion of the components deformation, or hit the fins.

(3) After the steam heater is installed, clean up the debris, Steam (heat Exchanger) Electric Heater including all the places, to prevent clogging the fins, affecting the normal operation.

(4) steam heater is not used, the internal water should be drained clean, so as not to freeze the tube in winter, affecting the use. ,

1, the steam heater is the use of boiler steam as a heat source to heat the air, and its design is the steam condensation process of exothermic process for the design is to make the superheated steam condensed into saturated steam, and then condensed into a saturated heat, heating Steam to the outside of the spiral finned tube to produce a stable phase transition exothermic process, the release of all the latent heat of gasification, Steam (heat Exchanger) Electric Heater the air heated to condense into saturated water discharge.

2, the use of tube cluster modular structure, the use of steel and aluminum composite spiral fins composed of tube row composed of heat transfer monolithic, single or a number of heat transfer monolithic parallel into groups, Steam (heat Exchanger) Electric Heater each group after the composition of the steam heater. String, parallel heat exchanger with modular building structure, small size, compact structure, easy maintenance and replacement.

3, steam heater from the shell, into the steam pipe header, hydrophobic pipe header, tube fixed plate, spiral fin tube bundle, hydrophobic pipe and hydrophobic thermal expansion elbow, positioning casing, Steam (heat Exchanger) Electric Heater duct transition section and duct flange Part of the composition.
