一、前言 稳定燃烧低等级和劣质煤粉,电站锅炉低负荷稳定运行及节省点火用油,开发水煤浆应用技术,这些都是节能工作中的重要方面,但都又面临着因之而引起的燃烧问题需要解决.随着各国能源政策的变化,燃料结构随之变化,水煤浆、低等级和劣质煤以及低热值燃料的开发利用,传统的稳定火焰方式渐感不足,从而要求燃烧技术有个发展.国内外在燃烧新技术的探索上进行了不少的工作,有的取得了成绩.作者于1985年提出了环形逆向分布射流稳定燃烧水煤浆和煤粉新方式.
I. Preface Steady combustion of low-grade and inferior pulverized coal, stable operation of power plant boilers at low load and saving of ignition oil and development of CWS application technologies are all important aspects of energy-saving work, yet they all face the same problem Of the burning problems need to be addressed.With the changes in national energy policy, the fuel structure will change, the development and utilization of coal-water slurry, low-grade and low-quality coal and low calorific value fuels, the traditional steady flame approach gradually less than adequate, requiring combustion technology A lot of work has been done on the exploration of new technology of combustion at home and abroad, and some achievements have been made.The author put forward a new way of stabilizing the combustion of CWS and pulverized coal by annular reverse jet in 1985.
