The prediction of some pulverized bituminous coal flames in a furnace

Abstract A bituminous coal-firing prediction procedure developed for a cement kiln is applied to the long coal flame trials of the International Flame Research Foundation. The work was prompted by the inability to test the procedure for real kilns due to the absence of data. The procedure, which is a development of an earlier Imperial College coal-firing code, handles the combustor aerodynamics, heat transfers, and reaction. All the essential phenomena, including CO formation and burnout, are modeled. The predictions of temperature, and O 2 and CO 2 and CO concentrations are compared with the data. Given the complexity of the many processes being modeled as well as the difficulty of the experiments, we consider these comparisons to be remarkably good.
