A linear programming model is presented for use in calculating the minimal cost to operate power plant SO2 removal systems. The following fuel related costs were included: coal purchasing, physical coal cleaning, UMW contribution, coal transportation, power plant operation and maintenance, flue gas desulfurization, and ash disposal. The model is bound by demand, environmental, and operational constraints. The model is used to compare alternative methods of achieving a given SO2 output. The results are sensitive to power plant location, coal purchase costs, and to variations in the variety of coal in the fuel mixture; slightly sensitive to flue gas desulfurization costs; and, insensitive to the other cost factors.
