Review of the Burner in Industrial Pulverized Coal Boiler

燃烧器作为煤粉燃烧技术核心关键设备,主要作用是将燃料与空气合理混合,使燃料稳定着火并形成某种流场以利于后续完全燃烧。实现安全节能环保燃烧,必须根据燃料的特性,选择合理的燃烧器类型及布置形式。因此,本文介绍了国内外几种典型的旋流燃烧器的分类及其特点,并总结了旋流燃烧器的发展趋势。

As the key equipment for the pulverized main role in mixing fuel and air reasonably in order to coal combustion technology, the burner is playing a make the fuel ignite stably, form some kind of flow field and then ensure subsequent combustion. In order to complete such a burning, which is safety, energy- saving and environmental; it is necessary to select a reasonable type and layout of the burner according to the properties of the fuel. Thus, several typical classifications and characteristics of the swirl burner was presented, and the development trend of swirl burner was also summarized.
