摘要
作者通过考察煤粉气流在着火前区域中的加热过程，提出了一种分析煤粉加热至着火的新方法。与传统的计算着火加热的方法不同，此方法着重考虑了煤粉着火所必需的孕育时间及煤粉非稳态加热的延迟时间，对深入分析煤粉气流的加热及着大过程有一定的理论意义。
Abstract Based on observations made of the heating process of coal particle air jets inthe preignition regions, the author suggests a new method for analysing the heating process of coal dust up to the point of ignition. Distinct from the conventionalway of calculating heating and ignition, this method in particular considers theincubation period required by pulverized coal before ignition and the time lag of unsteady heating which have a certain theoretical significance for further studieson the heating and ignition process of coal particle air jets.
