前言我国电厂燃用煤种复杂,煤质变化也较大。不同煤种着火性能,迄今只能根据挥发分含量,参考灰分,水分做大致的估计,没有一个比较可靠的评价方法。所以,为判别较为难烧的煤种如无烟煤、贫煤、多灰分的低质煤等,是否好烧,常常采用试烧的办法,耗费人力物力较大。我们在国内外资料[1、2、3、4]的基础上采用热失量方法来研究煤的挥发分析出过程及燃烧过程的一些特性。 Preface China’s coal-fired power plant complex, coal quality changes are also larger. Ignition performance of different coal, so far only based on volatile content, reference ash, water to make a rough estimate, there is no more reliable evaluation method. Therefore, in order to determine the more difficult to burn coal, such as anthracite, lean coal, ash and other low-quality coal, whether it is good to burn, often using the test method, consuming more manpower and material resources. Based on the domestic and international data [1, 2, 3, 4], we use the method of heat loss to study the volatilization process of coal and some characteristics of the combustion process.
