微油点火是国家节能减排重点推荐的节能措施之一,各大型火电机组纷纷应用微油点火技术来减少启动过程的燃油消耗,但LNASB燃烧器由于有中心风的存在,使微油点火改造过程中燃烧器改动量非常大,必然影响着燃烧器正常性能。文章从扬二厂#4炉LNASB燃烧器微油点火系统改造讲述了该型燃烧器的改造可能性、改造调试过程、改造后燃烧器特性变化及节能效果。
Micro-oil ignition is one of the most recommended energy-saving measures for energy saving and emission reduction. All the major thermal power units use micro-oil ignition technology to reduce the fuel consumption during start-up. However, due to the central wind, the LNASB burner rejuvenates the micro-oil ignition Burner changes in the process is very large, will inevitably affect the normal burner performance. This article describes the revamping of the LNASB burner micro-oil ignition system of # 4 furnace in Yangzhou Plant. It also describes the possibility of retrofitting this type of burner, retrofitting the commissioning process, changing the burner characteristics and saving energy.
