The test of burning Coal Water Slurry at a single corner ...

A coal-water slurry fuel (CWSF) program is being undertaken to determine if CWSFs prepared from cleaned coal (containing approximately 3.5 wt.% ash and 0.9 wt.% sulfur) can be burned effectively in a heavy fuel oil-designed industrial boiler without adverse impact on boiler rating, maintainability, reliability, and availability.

CWSF is made from coal, water, and chemical additives. Input coal must have a grade of at least 4,500 kc/kg in order to qualify for the production of CWSF. Water does not need to be pre-processed prior to mixing with coal and depending on the source and its content, industrial waste water may be used directly in the production of CWSF.
