This report presents the results of computer modeling conducted by Argonne National Laboratory (ANL) to simulate the heat transfer that results from burning coal in a mixture of CO/sub 2/ and O/sub 2/ rather than in air. A one-dimensional model was developed and used to simulate results for a coal-air burn and for burns using three different CO/sub 2/-to-O/sub 2/ ratios: 3.65:1, 2.42:1, and 2.23:1. These simulation results are compared with experimental results for the same four cases. We find that the ANL model effectively predicts heat transfer in a coal-air burn and in the three CO/sub 2//O/sub 2/ burns. Both the model predictions and the test observations also demonstrate that using a CO/sub 2//O/sub 2/ mixture, in a ratio between 2.42:1 and 2.23:1, as the oxidizer imitates the heat-transfer results of a conventional coal-air burn. These findings lend further credence to the feasibility of burning coal in CO/sub 2//O/sub 2/ rather than air, a new concept being investigated by ANL. One principal motivation for the investigation is to find a way of suppressing harmful combustion effluents. Another is to determine the feasibility of recycling part of the combustion products (CO/sub 2/, principally) back to the combustion process and also of recovering saleable CO/sub 2/. 11 refs., 9 figs., 5 tabs.
