Jan 23, 2017 · CWSF is 55%-70% fine dispersed coal particles and 30%-45% water. Coal particles suitable for diesel fuel replacement typically need to be less than 20 micrometers in diameter. CWSF is used at the place of oil and gas in any size of power stations. It is most suitable for existing gas, oil, and coal fired boilers.

Water-coal slurry as an alternative to natural gas and

Coal water slurry fuel (CWSF) represents a feasible method for burning coal in boilers designed for oil and natural gas. However, oil- or gas-fired boilers at Army plants cannot be converted to bum CWSF unless the fuel burner is redesigned. This evaluation of test and prototype burners can help Army engineers design Army CWSF conversions.
