Charcoal-Water Slurry Fuel
What?
Coal water slurry fuel, or CWSF, is a viscous, black liquid that can be produced by mixing finely ground coal (typically less than 20 microns in size) with water. Some chemical additives are required to keep the coal particles from settling out of solution. CWSF can be a substitute for diesel in properly modified furnaces or boilers. More experience exists for stationary applications and heating while the use in internal combustion engines is more difficult.
