Ash hopper dust removal electric heating belt

The main application of electric heat tracing system in waste incineration power plants is to prevent the fly ash from condensing on the equipment surface after waste incineration. In general, fly ash comes out of the lower part of the reactor and passes through the ash hopper of the dust collector. From the lower part of the ash hopper, it passes through the screw conveyor and chain conveyor to the bucket elevator. Fly ash is lifted to the upper part of the ash silo by a bucket elevator and stored in the silo. There is an ash unloading system at the lower part of the ash silo. Normally, these devices, as well as their associated pipelines and valves, require an electric heat tracing system. However, for ash hoppers, ash silos, and reactors, only lower heat tracing may be required.
Under normal circumstances, the operating temperature of fly ash is around 250 degrees Celsius, which is also the exposure temperature of the electric tracing system. Fly ash will condense at around 120-130 degrees Celsius. If a large amount of fly ash condenses on the surface of the equipment, it will hinder normal operation. Therefore, an electric tracing system is required, and this temperature is the maintenance temperature of the electric tracing system. Generally speaking, during normal production, electric tracing does not work. The electric tracing system is only turned on when the equipment is not running to ensure that it can work properly when restarted.

Overview of self limiting temperature electric heating belt

　　Self limiting temperature electric heating strip, also known as self controlled temperature electric heating strip, is a new generation of strip constant temperature electric heating product. It is composed of polymer conductive carbon particles and two parallel busbars with an external insulation layer. Its PTC heating element has a high positive temperature coefficient and is connected in parallel.

Characteristics of self limiting temperature electric heating belt

　　The self limiting electric heat tracing belt can automatically limit the heating temperature and adjust the output power according to the temperature of the heat tracing body; Can be cut arbitrarily or extended within a certain length range for use; Allow multiple overlaps without the concern of high temperature overheating and burning; Easy to maintain and energy-efficient.
