Combustion of anthracite culm in a fluidized bed boiler - NASA/ADS

The Department of Energy is sponsoring several projects to use anthracite culm, a coal waste material, as a low cost fuel to generate steam in a fluidized bed combustion (FBC) boiler system. These projects involve steam generation units ranging from 20,000 pph for manufacturing processes to 100,000 pph for district heating. One of the projects which is discussed in this paper is directed at
