Mathematical modelling of the coal stockpile self-heating

A simulation of the self-heating process occurring naturally in coal beds was carried out for a coal stockpile from Lupoaia (Romania). In order to obtain realistic results, meteorological data collected on site was used. Thermo-physical and chemical properties of coal used in

Coal Stockpile Monitoring - Agile Microsys

Coal storage in large coal piles brings with it the risk of spontaneous fires. As always, prevention is better than cure. A thermal imaging camera from FLIR Systems helps to ensure safety. The system provides a cost-effective solution for continuous, remote monitoring of temperatures in the coal piles.

Gaseous emissions from coal stockpiles - EE Publishers

Gas emissions from coal stockpiles are negligible compared to coal-fired power plant emissions; however caution should still be taken since some of the gases are toxic and explosive. The stockpiling of coal is carried out at a number of points along the transport chain to the end user – at coal mines; coal preparation […]

Frozen Coal Piles - Myth, or Real Problem? - America's Power

Once coal arrives at the plant site, it is either sent directly to the plant via conveyor belt or stored in piles. A typical coal-fired power plant has 70-80 days of coal supply stockpiled onsite. [ii] Bulldozers constantly manage the pile, keeping its height and size at proper levels and breaking up frozen areas.

Coal preparation plant - Wikipedia

A coal preparation plant is a facility that washes coal of soil and rock, crushes it into graded sized chunks, stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships. The more of this waste material that can be removed from coal, the lower its total ash content, the greater its market value and the lower its transportation costs.
