The SCFBC is basically a countercurrent contacting unit of downward moving solids with the hot combustion products moving up the stages. Each contacting stage is a shallow fluidized bed providing intimate contact between gas and solids. The design of SCFBC's requires rigorous determination of temperatures, stream flow rates, and heat transfer rates at each stage. The determination is made by solving material balance, energy balance, and appropriate rate equations for each stage. In this work a technical and economic evaluation of the SCFBC is presented. Analysis of an SCFBC producing 75,000 Ib/hr steam at 200psig is presented with respect to its thermal efficiency, carbon combustion efficiency, sulfur capture efficiency, and sorbent utilization. Effects of the Ca/S ratio on the percent sulfur retention, and carbon burnout efficiency, and effects of stack gas temperature on plant thermal efficiency, total capital costs, and unit cost of steam, and effects of boiler size on the total capital cost and on the unit cost of steam are presented. Effects of variations in cost of operating parameters, e.g., water, sorbent, fuel, etc., on the steam cost are discussed. |
