机械雾化微油点火小油枪在300 MW亚临界控制循环锅炉中的应用

摘要

Aiming at the problems of the oil consumption of oil ignition and pol ution problems seriously in the old power station boiler,The principle,auxiliary system,structure and system composition of micro-oil ignition burn-er were expounded. The application of tiny-oil ignition burner in Laicheng Power Plant was introduced. Aiming at the problems occurred in operation,some relevant improvement measures were proposed. The result proved the fuel saving ratio achieving 86% after the transform of micro-oil. It provided reference for similar boiler oil-saving project.%针对传统电站锅炉点火油枪耗油量大、燃尽率低、污染大等问题，阐述了微油点火燃烧器的工作原理、结构和辅助系统，介绍了微油点火在莱城电厂的实际应用情况，并对运行中存在的问题，提出了相应的改进措施。实践证明，微油点火改造后，节油率达到了86%，为电站锅炉节油降耗提供了技术支持。
