Pulverized coal vs. circulating fluidized bed; An economic comparison
- Babcock and Wilcox Co., Barberton, OH (USA)
As the power industry looks to the 1990s for expanded steam generation capacity, boiler owners will continue on their long-standing assignment to evaluate and select the best, lowest cost alternative to meet their energy needs. For coal-fired plants, this evaluation process includes pulverized coal-fired boilers (PC) and circulating fluidized bed boilers (CFB). The cost difference between these products is site specific and depends on several variables, including: boiler size, pressure, and temperature; operating variables, such as the costs for fuel, auxiliary power, SO{sub 2} reagent, and ash disposal; capital cost; and financial variables, such as evaluation period and interest rate. This paper provides a technical and economic comparison between a pulverized coal-fired boiler and circulating fluidized bed boiler.
