等离子煤粉点火在LNASB旋流式燃烧器上的应用

Application of Plasma Ignition Technique in LNASB Burner

介绍了烟台龙源电力技术有限公司开发的等离子煤粉点火及稳燃系统在大唐国际托克托发电有限责任公司应用的情况。这是等离子点火技术首次在LNA SB低NOx轴向旋流式煤粉燃烧器上获得应用,本文对等离子的应用情况作了全面介绍,针对着火不好的问题进行了数值模拟分析并依此进行了改造,取得了良好效果。它的应用使燃油消耗大大下降,节油经济效益十分可观。

This paper introduces the application of plasma ignition and burning stabilizing system developed by Yantai Longyuan Electric Power Technology Co. Ltd. in Datang International Tuoketuo Power Generation Co. Ltd. This is the first application of plasma ignition technique in LNASB. After implementation of plasma, numerical simulation analysis is given against unsteady ignition and corresponding renovation is carried out. The application has greatly decreased oil comsumption and obtained enormous economical benefits.
