The report gives results of a study to evaluate the technical and economic impact of designing wall-fired pulverized-coal units to incorporate dry-sorbent sulfur control technology (LIMB). Conventional (non-LIMB) units were set up in three sizes (200, 400, and 600 MW) to burn a low-sulfur (0.48%) subbituminous fuel. LIMB units were then set up to achieve 70% SOx removal using dry sorbent injection. Standard cost estimating procedures were used to evaluate the cost differentials between the conventional and LIMB units. These cost data were used to establish removal cost trends as a function of calcium-to-sulfur (Ca/S) mole ratios and boiler size. The study concluded that it is technically feasible to achieve 70% sulfur removal in a unit burning low-sulfur fuel using only dry sorbent injection. The results also showed that Ca/S ratios between 2.8 and 3.5 can be accommodated without radical alterations to state-of-the-art boiler configurations.
