A characterization of pressurized fluidized-bed and pulverized coal fired power plants
This paper presents the major technical and economic characteristics of steam- and air-cooled pressurized fluidized-bed (PFB) power plant concepts along with the characteristics of a pulverized coal fired power plant equipped with an adipic acid enhanced wet-limestone flue gas desulfurization system. The conceptual designs were prepared to satisfy a set of common groundrules that were developed for the study. The power plants are of the grassroots type, located on a generic plant site. The designs incorporate technological advances available for commercialization in the 1990 time frame. The net power outputs of the base case plants, using Illinois number6 coal, range from 502 MWe for the pulverized coal fired plant to 554 MWe for the air-cooled PFB plant. The net power plant heat rates vary from 9,725 Btu/kWh for the pulverized coal fired plant to 8,710 Btu/kWh for the steam-cooled PFB plant. For the economic groundrules set for the study, the pulverized coal fired plant utilizing an advanced flue gas desulfurization concept had the lowest specific capital cost and lowest levelized cost of electricity. However, utility and site specific conditions could materially alter the relative merits of the various concepts in a given utility application.
