Benefits
The presence of water in CWS reduces harmful emissions into the atmosphere and makes the coal explosion-proof. By converting the coal into a liquid form, delivery and dispensing of the fuel can be simplified.
Because of the relatively low cost of coal when compared to other energy sources, CWS is a very competitive alternative to heating oil and gas. Depending on geographical area the price per unit energy of CWS may be 30% to 70% lower than the equivalent oil or gas.
Low emissions and low BTU cost (Gcal or MWh) make CWS very cost effective and environmental friendly fuel for heat and power generation.
One side benefit of the Coal Water Slurry production process is the separation of non carbon material mixed with the coal before treatment. This results in a reduction of ash content to as low as 2% for the treated Coal Water Slurry Fuel, making it a viable alternative to Diesel fuel #2 for use in large stationary engines or diesel electric locomotives.

Famous quotes containing the word benefits:
“It is too late in the century for women who have received the benefits of co-education in schools and colleges, and who bear their full share in the world’s work, not to care who make the laws, who expound and who administer them.”
—J. Ellen Foster (1840–1910)
“It is with benefits as with injuries in this respect, that we do not so much weigh the accidental good or evil they do us, as that which they were designed to do us.—That is, we consider no part of them so much as their intention.”
—Laurence Sterne (1713–1768)
“While greedy good-doers, beneficent beasts of prey,
Swarm over their lives enforcing benefits ...”
—Robert Frost (1874–1963)
