Computational tools for pulverized-coal combustion. Third quarterly report, October 1981-December 1981
This report summarizes the work conducted to develop and verify a computer code capable of modeling the major aspects of pulverized-coal combustion. Achieving this objective will lead to design methods applicable to industrial and utility furnaces. The combustion model (COMO) consists of a number of relatively independent modules that represent the major processes involved in pulverized-coal combustion. These modules will be continually upgraded over the course of the contract. Three distinct versions of the COMO will be developed over the duration of the contract. Version 1 of COMO will model all of the major features of pulverized-coal combustion but with a number of simplifying assumptions. It will be used primarily to determine a satisfactory means of integrating the numerical models of the combustion processes into an overall combustion model, since this is perhaps the major challenge. Later versions will relax these assumptions and incorporate state-of-the-art combustion information. Guidelines were prepared and reviewed to allow process modules to be developed relatively independently, while providing for the subsequent integration of these modules into COMO. The formulation and coding of the Version 1 gas-phase turbulence, chemistry and radiation models were completed. Test cases were run for each model, and good agreement was obtained with other analyses and with data when available. A formal method for documenting COMO was investigated, and preliminary specifications were developed.
