Abstract
A method for the repowering of an existing coal-fired facility used in the generation of electric power which makes the facility more efficient while reducing its emissions in a cost-effective manner using the following steps: a) processing the coal in use to co-produce a clean liquid fuel and a clean low Btu gas; b) replacing the pulverized coal burners of the boiler contained in the facility with burners adapted to burn low-Btu gas; c) burning clean low-Btu gas in the boiler instead of coal; d) making up the derate of the boiler by the addition of efficient combined cycle power generation; and e) crediting the revenue derived from the sale of the liquid fuel co-produced to the existing facility to render such repowering commercially viable.
