This study compares the capital and operating costs of two different industrial boiler technologies, each producing 250,000 lbs steam/hr: Fluidized Bed Combustion (FBC) and Pulverized Coal (PC) combustion used in conjunction with a limestone Flue Gas Desulfurization (FGD) system. Three separate turnkey plant designs have been completed. Two of these plant designs incorporate FBC technology and have been designated FBA-16 and FBV-16. The first FBC design (FBA-16) contains two shop assembled, rail-shippable, fluid-bed boilers capable of producing 125,000 lbs/h each. The second plant design (FBV-16) utilizes a single fluid bed boiler shipped by rail in large sections for field assembly. This single unit is capable of producing 250,000 lbs/h. The third plant design utilizes a conventional pulverized coal (PC) boiler used in conjunction with a C-E Air Quaity Control System (AQCS) limestone scrubber. The FBA-16 and FBV-16 fluid bed designs were found to be competitive with the conventional unit. Capital costs were generated for the three turnkey plant designs just described. The FBA-16, FBV-16, and Conventional Unit plant designs have associated capital costs of $24.4, $22.8, and $24.7 million, respectively. A substantial cost reduction can be realized for plant capacities less than 180,000 lbs steam/h by incorporating a single FBA-16 type boiler. The operating costs for the bed designs are close enough to be considered similar when considering the nature of the study. The efficiency of the fluid bed plant designs can be increased and required capital equipment reduced by improvements to the plant design. Some potential design modifications are outlined. Extensive design and background research was prformed to increase the validity and relevance of this report.
