The air duct heater is mainly used to heat the required air flow, from the initial temperature to the required air temperature, the temperature is as high as 850°C. It is widely used in scientific research and production laboratories such as aerospace, weapons industry, chemical industry, universities, etc. It is especially suitable for the test of automatic temperature control and large flow high temperature combined system and accessories. The air duct electric heater is composed of the main body and the control system. The heating element is made of stainless steel tube, high temperature resistant alloy wire and crystalline magnesium oxide powder. The controller adopts a constant temperature system composed of advanced digital circuits, integrated circuit triggers, adjustable high back pressure thyristors and other components to ensure the normal operation of the electric heater.
The air duct heater plays a very important role in the life and production process. Its appearance greatly saves the management cost in the electric heating process, and plays a very good auxiliary treatment effect on the production and lifestyle of the enterprise. With the development of China’s power electronics industry and the introduction of some new technologies, thermal power plants have changed the original hydraulic ash removal to dry ash removal, which not only saves a lot of research water and grain fields, but also makes coal ash reproduced by humans. contribution. Air duct electric heaters can use coal ash to make the company’s cement, coal ash bricks and highways, and can also improve the pollution caused by the social environment and benefit the people.
The air duct heater is a new type of material heating technology equipment used in the ash removal system of coal-fired power plants. It is suitable for power station air quality transmission chute gasification wind heating, electric precipitator ash hopper gasification wind and ash storage gasification wind heating time . The equipment is composed of the main body of the air electric heater and the control information system. The system is mainly composed of advanced digital display circuit, integrated application circuit trigger, high back pressure thyristor and other materials, temperature measurement adjustable and constant temperature processing system. Manufacturers of air duct heaters need to ensure the normal and economical operation of electric heaters. Generally, straight pipes are used for heat dissipation components instead of U-shaped, which can be easily installed and disassembled with various special sheet metal hands.
