摘要
本文对煤粉气流的火炬点火机理进行了探讨,并建立了直流煤粉气流火炬点火的近似数学模型,该模型的理论计算值与试验结果基本吻合,可用于煤粉气流点火参数的确定和点火装置的设计.
Based on the studies of the ignition mechanism of coal-air flow by flame torches, an approximate mathematical model is proposed. The theo-retical results tally with the experimental results. The results can be used for the design of combustor and the selection of igniting parameters of pulverized coal-air flow.
