Empirical models of emissions and energy efficiencies of coal-fired fluidized bed power plants

Abstract

Mass and energy balances of fluidized bed energy technologies are to a significant degree dependent upon the specific design being investigated. It is difficult to make any generally accurate comments. about these balances. This study attempts to solve this difficulty by displaying a large amount of available data, especially on parametric experiments, for the specific designs. To the extent that generalizations about the efficiencies and emissions of these cycles are.possible empirical correlation models have been developed, along with measures of the predictive quality of these models over existing data bases. These empirical correlations consist of probabilistic models that have been fit to published experimental data. In several instances, there have been comparison of these empirical models with available analytic models. In the cases of unavailable experimental data, such as for the potassium topping cycles, models have been fit to analytic data. Although the overall scale of this effort was very small compared to other fluidized bed reviews, such as those performed at Babcock and Wilcox, Burns and Roe, and Battelle-Columbus, the empirical models are new and in the narrow scope of this study some of-the literature reviews are more comprehensive than others available at this time. Extensive bibliographic research and identification-of on-going projects is also included in this report.
