Development history and life in the development of the airway electric heater

The airway electric heater is mainly used to heat the required air flow from the initial temperature to the required air temperature, higher than 850 ° C. It has been widely used to many research and production laboratorys such as aerospace, weapons industry, chemical industry and colleges. The airway electric heater is installed on a fixed bracket with a stainless steel electric heating tube outer fin. The wind turbine electric heater can be inlaid into the air or static pressure box. The power supply can be dissipated and the thermal efficiency is high. The heat is well refined, the service life is long, safe and reliable, the unit itself is equipped with a high temperature overheating protection device, set The temperature is automatically powered off when the temperature is reached at 95 ° C, and the heater is reached when the temperature value is reached. The airway electric heater is particularly suitable for automatic temperature-controlled temperature and large flow high temperature combined systems and accessories tests. The wind-type electric heater has two parts: the body and control system, the heat generating element is used to protect the casing, high temperature resistance of the metal, and the crystalline magnesium oxide powder is formed by the compression process; the control portion adopts advanced digital circuitry, integrated circuit trigger Make up the temperature and thermostat system to ensure the normal operation of the electric heater. The air-duct electric heaters play a major role in life and production. It has greatly conserved cost consumption during electric heating, and has a good auxiliary role in production and life. With the development of the electric industry and room heater
introduces new technologies, in the fire power plant, the original hydraulic power is changed to dry ashes, so that the large amount of water, grain field, can also contribute to the cake . The air-channel electric heater can be used to make cement, coal ash bricks, and improve environmental pollution, benefiting people. The wind-type electric heater is a new type of heating device used by the coal-fired power plant, which is suitable for the air transport of the electric station air transport, and the electric precipitator is too hot and the gray gasification wind heating. The device consists of two parts: air electric heater body and control system. The control section adopts advanced digital circuitry, integrated circuit trigger, high-counter-controlled silicon, etc., can be modulated, constant temperature system, ensuring the normal operation of the electric heater. The heat generating element uses a straight tube type to replace the U-shaped structure, which is convenient to install and disassemble the special sheet metal. The airway electric heater is a stainless steel pipe, a tie threaded fin, lateral arrangement, mounting, and air tube electric heater for easy repair, group control. Several sets of heating tubes were arranged in a few layers to increase the heat exchange rate and improved the heating effect. The casing is in the frame, and the outer casing uses high quality galvanized sheets. For stainless steel pipes, outer threaded fins, horizontal arrangement, mounting, and wind pipe electric heaters are maintained and can be packetized.
