导言许多电厂运行人员都曾不安地注意到,当使用煤种从一个矿源转变至另一个矿源时,由于燃烧和结渣特性不同,往往会出现麻烦。其原因一般归于煤的某种特性的差别。随着进口煤越来越多地使用以及煤种与煤源日益频繁地改变,来自世界各地矿区硬煤的各种特性,以及煤与煤之间的特性差别问题对燃烧器及炉膛设计的影响越发显得重要。重要的是应该知道,尽管观察和考虑得
INTRODUCTION Many plant operators have uneasily noted that when coal is used to shift from one source to another, problems often arise due to differences in combustion and slagging characteristics. The reason is generally attributed to the difference of certain characteristics of coal. As imported coal is used more and more and coal and coal sources are changed more and more frequently, the various characteristics of hard coal from mining areas around the world, as well as the differences in characteristics between coal and coal, have implications for burner and hearth design More and more important. It is important to know that, despite the observation and consideration,
