摘　　要：大型火电厂锅炉的点火和稳燃在传统上都是采用燃烧重油来实现的。随着油价的不断提高,火力发电燃油成本越来越高。为了减少重油的耗量,引进等离子点火技术。本装置利用直流电流在介质气体接触引弧,并在强磁场下获得稳定功率的直流空气等离子体。该等离子体在燃烧器的一次燃烧筒中形成局部高温区,煤粉颗粒通过高温作用,并使煤粉颗粒破裂粉碎,从而迅速燃烧。本文详细的介绍等离子点火的构成和工作原理,以及在环保、经济方面发挥的作用。The large-scale thermoelectric power station boiler ignition and bums in the tradition all is steadily uses the burning heavy oil to realize~ Along with the oil price unceasing enhancement, The thermoelectricity generation fuel oil cost is more and more high. In order to reduce the heavy oil the consumption quantity, Introduction plasma ignition technology~ The device uses the DC cur- rent in the medium gas contact are and to obtain the stable power of the DC air plasma in the strong magnetic field. The plasma is formed in a local high temperature region in a burner, and the pulverized coal particles are in high temperature, and the pulverized coal particles can be broken and shattered, and thus, the coal powder can be quickly burned. This article detailed introduction plasma ignition constitution and the principle of work, As well as the function which in the environmental protection and the economical aspect displays.
