摘要

新疆准东高碱煤是优良的动力煤种，但大比例燃用高碱煤时锅炉设备易发生严重结渣问题，燃用准东煤锅炉的燃烧系统设计原则与提高低负荷稳燃能力的传统技术措施相矛盾。为解决该问题，基于煤粉稳定燃烧机理，研究了节油点火燃烧器布置优化、中层燃烧器交错布置、煤粉浓度在线可调、燃烧器结构优化等措施。某燃用准东高碱煤的350 MW机组对冲燃烧锅炉深度调峰改造项目应用该技术，实现了不投油稳燃负荷低于18%额定负荷。

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.
