ABSTRACT:
The invention disclosed is for a combination of two processes to enable the clean burning of coal in a coal water mixture. First the coal is ground and then treated with a desulfurizing microorganism to desulfurize the coal. After separation the coal is formulated into a coal water admixture in requisite quantities of water to coal, and with proper inclusion of additives, is combusted in a suitable furnace equipped with a means to burn a coal-water mixture. The desulfurized coal, after treatment with a select microorganism, will contain less than 1.0 wt % pyritic (inorganic) sulfur, be low in ash content and be cleanly combustible to capture its latent heat values.
