Steam Heaters Have High Heat Transfer Coefficient
Oct 24, 2017



Steam heaters as a heating device, now in many ways have been a lot of applications. Because it is different with the air heater, so today we need to have a good look at what in order to know what kind of heater should be used, the analysis is described below.

Steam heater is made of steel and aluminum composite finned tube as a heat transfer element, 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 is the use of boiler steam as a heat source to heat the air, the design is the steam condensation process of heat for the design basis, is to make the superheated steam condensed into saturated steam, and then condensed into a saturated water, heated steam Spiral finned tube outside the transverse air to produce a stable phase transition exothermic process, Steam (heat Exchanger) Electric Heater the release of all the latent heat of gasification, the air heated to condense into saturated water discharge.

 The use of steel pipe composite structure composed of steel and aluminum composite spiral finned tube composed of heat transfer monolithic, single or several heat transfer monolithic parallel group, Steam (heat Exchanger) Electric Heater each group in series after the composition of the steam heater. String, parallel heat exchanger with modular building structure, small size, compact structure, easy to repair replacement.

Steam heater from the shell, into the steam pipe header, hydrophobic pipe header, tube bundle fixed plate, spiral fin tube bundle, hydrophobic pipe and hydrophobic thermal expansion elbow, positioning sleeve, Steam (heat Exchanger) Electric Heater duct transition section and duct flange and other components The

Steam heater specific features are:

(1) The heat transfer element uses the spiral fins, and the fins are integrally pressed once, 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 the wrong arrangement, so the heat transfer area, heat transfer coefficient is also high.

(4) pipe design distribution is very reasonable, Steam (heat Exchanger) Electric Heater and the air flow is very uniform.

(5) steam heater in the factory has been before the hydraulic 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, mainly to see whether the collision or injury, if damaged, should be repaired, and need to re-test and test.

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

(3) steam heater installed to clean up the clean debris, including all places, to prevent clogging fins, affecting normal operation.

(4) steam heater is not used, the internal water should be drained clean, Steam (heat Exchanger) Electric Heater so as not to freeze the pipe in winter, affecting the use.
