  • Coal Slurry: an Idea that Came and Went | WyoHistory.org

    During the coal boom of the 1970s, slurry pipelines were proposed as an alternative to rail transport. Coal would be crushed, then mixed with water to create a slurry and sent via pipeline to its destination, where the mixture was dried, then burned. When in the pipeline, the slurry moved along at a leisurely four miles an hour.

  • Coal and Water Pollution | Union of Concerned Scientists

    Water use. All coal plants rely on water. They function by heating water to create steam, which then turns turbines, generating electricity.. But the water must come from somewhere—typically a nearby river or lake. "Once-through" coal plants pump the water directly from a water source, heat it up, then discharge it back.The waste water is typically hotter (by up to 20-25° F) than the ...

  • Activated charcoal - Poison

    Activated charcoal is made by burning carbon-rich materials, such as wood, at very high temperatures to create charcoal. The resulting product is a black, odorless powder. The charcoal is then "activated" through a special process that makes lots of holes and crevices on the charcoal particles to increase surface area and available binding sites.

  • Coal Engine: Tank to Engine Fuel Delivery | A Crowbar and ...

    The downside to using a water-coal mix is that a good chunk of the energy in coal is captured by the water to steam process. From a conceptual stand point, it appears that the best method of fuel delivery is as a coal water slurry. The system is much simpler and less likely to break down however this is at the cost of available work energy.
