Coal water slurry fuel (CWSF or CWS or CWF) is a fuel which consists of fine coal particles suspended in water. Presence of water in CWS reduces harmful emissions into the atmosphere] makes the coal explosion-proof, makes use of coal equivalent to use of liquid fuel and gives other benefits
CWS consists of 55-70% of fine dispersed coal particles and 30-45% of water. Under the chemical additive influence, CWS become fluid coal-based fuel like oil. Density: 60-70, viscosity: 1200/mPa.s, average grading: 50µm, calorific value: 17-19MJ/kg. Coal particles suitable for diesel fuel replacement with good fluidity and stability, which can be stored and transported like oil. Safe and environmental friendly feature make CWS the best fuel to replace oil.

CWS is made from raw coal with good quality, which has many features, for example: low ash content, low sulfur content, low moisture content, high calorific value, high fugitive constituent and high ash melting point. These coal, include Gas coal, fat coal, gas-fat coal, 1/2 medium caking coal, can be taken as the raw material of CWS.
