Non-woven Fabric Heater Manufacturer RecommendationCompressed air heater is an electric heating device mainly used for heating gas streams. The inner cavity of the compressed air heater is equipped with multiple baffles (guide plates) to guide the gas flow, prolong the residence time of the gas in the cavity, thereby fully heating the gas, making the gas heating uniform, and improving heat exchange efficiency. The heating element of the compressed air heater is a stainless steel heating tube, which is made by inserting electric heating wires into a seamless steel tube, filling the gaps with magnesium oxide powder that has good thermal conductivity and insulation, and then shrinking the tube. When current passes through the high-temperature resistance wire, the generated heat diffuses through the crystalline magnesium oxide powder to the surface of the heating tube, and then transfers to the heated gas to achieve the purpose of heating.
Application scope:
Compressed air heater is a widely used heater. We commonly call it compressed air heater. Actually, it can be subdivided into many types according to different heating air, which can also be called duct-type compressed air heaters. The control part of the electric heater is a precision instrument. It should be handled with care during transportation, and impact and collision are strictly prohibited. The cylinder part should be lifted reasonably to avoid deformation and damage to internal heating elements. The compressed air heater and control cabinet should be placed in the warehouse and strictly protected from rain.
Working principle of compressed air heater:
High-temperature resistance wires are evenly distributed inside a high-temperature resistant stainless steel seamless tube, and the gaps are densely filled with crystalline magnesium oxide powder with good thermal conductivity and insulation properties. This structure is not only advanced and has high thermal efficiency, but also heats evenly. When current passes through the high-temperature resistance wire, the generated heat diffuses through the crystalline magnesium oxide powder to the surface of the metal tube, and then transfers to the heated part or air gas to achieve the purpose of heating.
The compressed air heater is mainly used to heat the required gas flow from the initial temperature to the required gas temperature, up to 800°C. It has been widely used in aerospace, weapon industry, chemical industry, universities and many other scientific research and production laboratories. It is especially suitable for automatic temperature control and large flow high-temperature combined systems and accessory tests. The compressed air heater has a wide range of applications: it can heat any gas, and the generated hot gas is dry, non-conductive, non-flammable, non-explosive, non-corrosive, reliable, and the heated space heats up quickly (controllable).
Technical characteristics of compressed air heater:Non-woven Fabric Heater Manufacturer Recommendation
1. Fast heating and cooling rate, up to 10°C/s, fast and stable adjustment. There will be no temperature lead or lag phenomenon of the controlled gas, causing temperature control drift, which is very suitable for automatic control.
2. High efficiency: up to 0.95 or more.
3. Good mechanical properties: Because its heating element is made of alloy material, under the impact of high-pressure gas flow, its mechanical properties and strength are better than any other heating element, which is more advantageous for systems and accessory tests that require continuous heating of gas for a long time.
4. Can heat gas to a very high temperature, up to 800°C, while the shell temperature is only about 50°C.
5. Durable and long service life up to decades when used in accordance with operating procedures.
6. Clean gas, small volume.
7. Multiple types of air electric heaters can be designed according to user needs.
8. Outlet temperature and flow are controllable, with variable frequency speed regulation.
9. Single unit power ranges from 2KW to 2000KW.
