摘要/Abstract

摘要： 介绍了等离子点火燃烧器的工作原理、结构和辅助系统配置。分析了等离子点火系统在四角切圆燃烧锅炉上应用时对应FSSS 控制逻辑的修改。阐述了锅炉冷态启动等离子点火操作步骤和等离子点火燃烧器投运的注意事项及其运行中存在的问题。针对机组启、停过程中燃烧消耗大量燃油的问题, 内蒙古华电包头发电有限责任公司600MW机组采用了等离子点火技术后，实现了机组冷态启动、热态启动、机组滑停并在运行中检修单台引风机、送风机、一次风机和空气预热器不投油，取得了良好的经济效益。

Abstract: The working principle and structure of plasma igniting burner were introduced, and the configuration of its auxiliary system was described. When the plasma ignition system is applied in tangentially fired boiler, the FSSS control logic needs some modification, and this modification was analyzed. The plasma ignition operating procedure was described; the matters needing attention while plasma ignition burner is putting into operation and the problems existing in its operation were pointed out. Aiming at great amount of oil consumption in unit startup and shutdown process, the plasma ignition technology was adopted in a 600MW unit of Inner Mongolia Huadian Baotou Power Generation Corporation Limited; and the unit cold start and hot start, the unit shutdown with variable parameters, the repairs of induced draft fan, forced draft fan, primary air fan and air preheater were realized without oil consumption, and good economical effects were obtained.

Key words: plasma device, working principle, auxiliary system, control logic, ignition control, practical application
