Coal preparation plant - Wikipedia

Front-end loaders and bulldozers can be used to push the coal into feeders. Sometimes front-end loaders are the only means of reclaiming coal from the stockpile. This has a low up-front capital cost, but much higher operating costs, measured in dollars per tonne handled. High-capacity stockpiles are commonly reclaimed using bucket-wheel reclaimers.

TENORM: Coal Combustion Residuals | US EPA

In a typical coal-fired boiler, coal is burned and the heat is extracted to generate steam. The steam is used to drive a turbine, which in turn, drives an electrical generator. Low pressure steam leaving the turbine is fed to a cooling system which extracts any residual heat and condenses the steam back to water.
