等离子点火技术是一种新型的燃煤锅炉点火及助燃技术。东莞玖龙纸业有限公司安装的210MW机组装有等离子点火系统。在调试和试运行中,遇到等离子点火系统的供电电源设计不当;启动电动给水泵时等离子发生器灭弧和跳磨煤机;油、煤火焰检测混淆;运行时等离子燃烧器挂焦超温;等离子燃烧器从“正常模式”切换到“等离子模式”时跳磨煤机;磨煤机无暖磨程序等问题。在对存在的问题进行了分析后,对相关的逻辑进行了改进和完善。
Plasma ignition technology is a new type of coal-fired boiler ignition and combustion technology. Dongguan Nine Dragons Paper Co., Ltd. installed 210MW unit equipped with plasma ignition system. During commissioning and commissioning, the design of the power supply for the plasma ignition system was improperly designed. When the electric feed pump was started, the plasma generator extinguished the arc and hopped the coal pulverizer. The confusion between the flame detection of oil and coal and the overheating of the plasma burner during operation ; Plasma burners to switch from “normal mode” to “plasma mode” hopper coal mill; mill without heating process and other issues. After analyzing the existing problems, the related logic is improved and perfected.
