I. SLFBFD10-500 Explosion-Proof Duct Heater Overview:
With the development of the power industry and the introduction of new technologies, thermal power plants have converted from hydraulic ash removal to dry ash removal, which not only saves a large amount of water resources but also allows coal ash to contribute to humanity again. Coal ash can be used to make cement, coal ash bricks, and build roads, while also improving environmental pollution and benefiting the people. The air electric heater in the dry ash removal equipment system produced by our company has been operating normally in many power plants and has received praise from experts.
II. SLFBFD10-500 Explosion-Proof Duct Heater Features and Applications:
The DYK series air electric heater for power station ash removal consists of two parts: the air electric heater and the control system. The heating element uses 1Cr18Ni9Ti stainless steel seamless tube as the protective sleeve, 0Cr27Ai7MO2 high-temperature resistance alloy wire, and crystalline magnesium oxide powder, formed through a compression process to ensure the service life of the heating element. The control part adopts advanced digital circuits, integrated circuit triggers, and high-voltage resistant thyristors to form an adjustable constant temperature and temperature measurement system, ensuring the normal operation of the electric heater. This product is suitable for power station air conveying troughs, electrostatic precipitator ash hopper gasification, and ash silo gasification.
