The raw coal is then fed into the pulverizer along with air heated to about 330°C (650°F) from the boiler. As the coal gets crushed by the rolling action, the hot air dries it and blows the usable fine coal powder out to be used as fuel. The powdered coal from the pulverizer is directly blown to a burner in the boiler.

2.1 Feedstocks. The conducted research was focused on the use of two waste-biomass feedstocks of high ash content and demanding chemical composition. Feedstocks before use were pelletized (6 mm outer diameter) to improve their density and homogeneity; however, due to the small size of screw feeders used in this lab-scale unit, the fuel …

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.

How coal is formed. Coal is formed when dead plant matter submerged in swamp environments is subjected to the geological forces of heat and pressure over hundreds of millions of years. Over time, the plant matter transforms from moist, low-carbon peat, to coal, an energy- and carbon-dense black or brownish-black sedimentary rock.
