Pressurized fluidized bed combustion (PFBC) of coal is undergoing demonstration and commercial deployment in the United States, as well as throughout the world. American Electric Power`s (AEP) bubbling PFBC 70 MW{sub e} Tidd demonstration program in Ohio and pilot-scale work at Ahlstrom Pyropower`s 10 MW{sub e} circulating PFBC at Karhula, Finland have demonstrated the advantages of PFBC technology. Development of uses for solid wastes from PFBC coal conversion systems is being actively pursued as part of the commercial demonstration of PFBC technologies. Ash collected from the low-sulfur subbituminous coal-fired Ahlstrom pilot circulating PFBC tests in Karhula, Finland and ash from the AEP`s high-sulfur bituminous coal-fired bubbling PFBC in Brilliant, Ohio were evaluated in laboratory and pilot-scale ash use testing at Western Research Institute (WRI). Ash use options evaluated for these PFBC ashes were construction-related applications, such as (1) cement production, (2) fills and embankment, (3) soil stabilization, (4) synthetic aggregate production, as well as an amendment for acidic and sodic soil and mine spoil.
