燃用高碱煤锅炉的宽负荷对冲燃烧技术研究及应用
Research and application of wide load opposed firing technology for high-alkali coal fired boilers
摘要
Abstract
Xinjiang high-alkali coal is a cost-effective power coal,but when it is used in large proportions,boiler equipment is prone to severe slagging problems.The design principles of the combustion system for boilers using Zhundong coal are inconsistent with conventional technical measures to improve low-load stable combustion performance.To solve this problem,based on the mechanism of stable combustion of pulverized coal,measures such as optimized layout of tiny oil ignition burners,interlaced arrangement of middle layer burners,online adjustable coal powder concentration and burner design optimization have been studied.The technology was applied in a 350 MW unit's deep peak regulation retrofit project using Zhundong high-alkali coal as fuel,and achieved a stable combustion load of less than 18％rated condition without oil injection.关键词
