2009-8-1 · Being a new-developed coal-based fuel, CWS is made of about 65–70% coal, 30–35% water and 1–2% additive. It has qualities just like oil and can be burned directly after sprayed. It is a kind of perfect fuel which can take the place of oil in many situations but has different characters from coal for its water content.
