| 摘 要： | 文中介绍了采用小型动态着火试验炉对多种单一煤及混煤的着火特性所进行的试验研究,测定了单一煤及混煤的着火特征温度,并对其进行了比较和分析,提出了混煤“等效挥发分”的概念.在上述试验研究的基础上,对混煤的着火机理进行了初步分析,并提出了混煤的着火模型。为混煤着火性能的进一步研究奠定了基础.为燃烧混煤的电站锅炉一次风配风提供了重要参考依据。

| Abstract: | In this paper,test investigation concerning various kindsof a single and mixed coals ignition characteristics temperaturemeasured by small—scale dynamic test furnace was presentedand its analysis and comparison was done,the“equivalentvolatile”concept was put forward.On the basis of above teststudy,ignition mechanism of mixed coal was analyzed initia-tively and its ignition modelling was put forward.It laid afoundation to further more study the ignition performance ofmixed coal and also provides an important reference's basisfor primary air in utility boiler fired mixed coal. |
