一、概述 我院接受了燃煤增压流化床(PFBC)燃烧试验研究的任务,在试验研究的同时,试图利用模型研究的手段,预测流化床的各种工作参数对燃烧过程的影响,以减少一些试验研究的工作量。由于流化床燃烧模型目前尚处于探索阶段,国际上发表的多是常压流化床燃烧(AFBC)模型,有关PFBC模型的文章只是个别而已。如1980年Sexena和Turek提出的PFBC综合模型,文章并未考虑床内气泡对流体动力学过程和燃烧反应过程的影 I. Overview Our laboratory has accepted the task of the combustion test of coal-fired pressurized fluidized bed (PFBC). At the same time, it attempts to predict the impact of various working parameters of the fluidized bed on the combustion process by means of model studies , To reduce the workload of some experimental research. Because the fluidized bed combustion model is still in the exploratory stage, most published in the world are atmospheric pressure fluidized bed combustion (AFBC) models, and the article on the PFBC model is only a few. Such as the PFBC integrated model proposed by Sexena and Turek in 1980, the article does not consider the influence of bubbles in the bed on the hydrodynamic process and combustion reaction process
