High Heat Transfer Coefficient Of Steam Heater
Aug 15, 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, Steam (heat Exchanger) Electric Heater and the analysis is described below.

The steam heater is a steel-aluminum composite fin tube as heat exchanger, so it combines the pressure resistance of the steel tube and the high thermal conductivity of aluminum, Steam (heat Exchanger) Electric Heater 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, and the heat transfer coefficient is high.

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

(3) The finned tube is the wrong column arrangement, Steam (heat Exchanger) Electric Heater 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, Steam (heat Exchanger) Electric Heater in order to prevent the distortion of components, or to touch bad fins.

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

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

Steam heater is the use of high-temperature steam to heat the low-temperature gas heat exchanger, mostly used in large-scale PTA projects Exhaust Gas expander heating, to achieve technological requirements temperature. For large-scale heaters, in order to save costs and the structure of their own needs, each heater can be two-stage series, the use of different materials, the use of two quality steam, to avoid energy waste, while saving the cost of manufacturing, for small heaters can be made into one, simple structure. Gas cooler, horizontal storage tank, Steam (heat Exchanger) Electric Heater air compressor class cooler, floating head heat exchanger, water cooler, composite pipe gas cooler, centrifugal compressor with pressure vessel-separator for metallurgy, air separation, pharmaceutical industry to provide heat exchanger, separator. In view of the different medium condition uses the high efficiency heat exchanging element, designs, manufactures the high efficiency energy-saving vessel equipment, Steam (heat Exchanger) Electric Heater in reduces the pressure drop, the heat transfer, separates the integration: guarantees the continuous operation: enhances the system and the whole machine efficiency aspect has the unique. For the public Works, defense, environmental protection industry to provide heat exchangers, separator tanks and other pressure vessel equipment. Material has carbon steel, stainless steel, non-ferrous metals.
