| 中文摘要 | in a slagging combustor or furnace, the high combustion temperature makes the molten slag layer cover the wall and capture the particles. if these particles contain combustible matter, they will continue to burn on the running slag. as a result, the total amount of ash deposition will be much greater than that in dry-wall combustors and the total heat flux through the deposition surface will change greatly. considering the limitations of existing simulation methods for slagging combustion, this paper introduces a new wall burning model and slag flow model from the analysis; of particle deposition phenomena. combined with a conventional combustion simulation program, the total computational frame is introduced. from comparisons of simulation results from several kinds of methods with experimental data, the conclusion is drawn that the conventional simulation methods are not very suitable for slagging combustion and the wall burning mechanism should be considered more thoroughly. |
