At such locations, the coal ember may ignite the coal dust around it and cause a coal dust explosion, which may lead to loss of life and downtime. Embers can reliably be detected only on the conveyor belt itself since at other locations, such as in a Stockpile, the ember may be buried under other coal.
Coal is the main component in thermal power station. The effective usage of coal leads to efficient power generation. The amount of coal and Fly ash should be handled properly in such a way that the production is not altered. B. Conveyor System For Effective Coal Handling System, the conveyor …
Fire-protection guidelines for: Conveyors transporting coal Conveyor systems in general have a fire risk due to external events and equipment failure. However the flammable nature of coal including the ability of some types to self ignite introduces an exceptional hazard requiring special consideration.
To date, coal conveyor fire protection systems have typically involved the use of line-/spot-type heat detection technology coupled with a sprinkler system. These components are generally hung ...
