Waste Incineration Plant Ash Hopper Electric Heat Tracing

Waste Incineration Plant Ash Hopper Electric Heat Tracing is a special heat trace solution based on MI heating cable for the ash hopper in waste incineration power plant to prevent ash condensing. The flying ash cooling in ash hopper in waste incineration power plant may cause ash solidification, compression or agglomeration and lead to the clogging of ash hopper.

Garbage incineration power plant is an environment-friendly garbage disposal method with its main principle putting life rubbish in the garbage incinerator combustion and using the generated steam to produce electricity, at the same time, adopting strict flue gas treatment method to make the waste harmless. Its role is to dispose the rubbish with the power generation as a by-product.

The process of waste incineration generates fly ash. The fly ash comes out from the lower part of the reactor passing through the dust hopper of the dust remover, from the lower part of the ash hopper, through the screw conveyor and chain conveyor to the bucket elevator, and the fly ash is lifted to the upper part of the ash hopper and stored there. There is an ash discharge system at the lower part of the ash hopper.

Because fly ash will condense at about 120-130 degrees, if a large amount of fly ash is condensed on the surface of the equipment, it will hinder the normal work. Therefore, heat trace is required for these operating equipment units and the corresponding pipes and valves, as well as the lower part of the ash hopper, to ensure the normal work of the equipment.
