PM 型燃烧器设计分析及其在低灰熔点无烟煤煤粉锅炉炉膛布置中的应用

Analysis on Designing of PM Burner and Its Application in Arrangement for the Low-ashfusion Anthracite-fired PF Boiler

日本三菱重工开发的PM 型燃烧器(PM 是Pollution Minimum 最小污染的缩写)对无烟煤的适应性已被国内不少动力工作者所重视.本文为了进一步研究其设计及结构机理,对PM 型燃烧器与其分配器的力学与燃烧动力学原理及其对低灰熔点无烟煤煤粉锅炉的适应性与其布置原理进行了分析.

The adaptability of PM(Pollution Minimun)burner toanthracite,which was developed by Mitsubishi Heavy Indus-tries Corp.,Japan, has been had an attraction for many do-mestic power workers.In order to further study its mecha.nism of design and construction,the analysis on the mechan-ies and combustion kinetics principle of PM burner and di-rider,its adaptability to the pulverized low-ash-fusion an-thracite-fired boiler and the tenct of furnace arrangementwere carried out.
