摘要

在新能源大规模消纳及国家“双碳”战略目标驱动下，新型电力系统的构建对煤电机组灵活运行提出了更高要求。然而，煤电机组在低负荷运行时面临燃烧稳定性下降、蒸汽参数偏离设计值等挑战。以某电厂600 MW亚临界切圆燃烧锅炉为研究对象，基于数值模拟方法，系统研究了锅炉在50%负荷下，将小粉仓乏气分别通入炉膛主燃区、还原区、燃尽区不同位置对炉内流场、温度场、组分浓度场以及屏区烟气温度的影响规律，重点分析了乏气通入炉膛不同位置对锅炉低负荷稳燃特性与烟温调控的协同作用策略。研究结果表明：将小粉仓乏气通入炉膛不同位置，炉内均能维持稳定的切圆流场组织及高温区域分布，其对锅炉低负荷稳燃性能未产生明显不利影响；将乏气通入还原区，可促使火焰高温区域适度上移，该特性有利于提升深度灵活调峰工况下蒸汽参数稳定性，烟温协同调控效果更优。研究通过数值计算分析获得了通过小粉仓乏气再利用实现锅炉低负荷稳燃与提升烟温协同调控策略，结果可为同类型火电机组宽负荷灵活调峰运行提供基础与依据。

Abstract

Driven by the large-scale integration of renewable energy and the national “dual-carbon” strategic goals

the construction of a new power system imposes higher requirements on the flexible operation of coal-fired units. However

coal-fired units face challenges such as reduced combustion instability and steam parameters deviating from design values during low-load operation. Therefore

in-depth research on coordinated control characteristics of low-load stable combustion and flue gas temperature in boilers is of significant importance for deep and flexible peak regulation. Taking a 600 MW subcritical tangentially fired boiler in a power plant as the object

the effects of injecting primary air exhaust gas from the pulverized coal conveying system into different locations of the furnace(main combustion zone

reduction zone

burnout zone) on the velocity

temperature and component concentration field

and the flue gas temperature at the platen zone are systematically studied under 50% load condition. The analysis specifically focuses on the synergistic influence mechanism of combustion organization on the combustion stability of the boiler and the regulation of flue gas temperature. The results indicate that injecting primary air exhaust gas into various furnace locations can form a stable tangential flow pattern and high-temperature zone

without significantly affecting the boiler's low-load combustion stability. Injecting the primary air exhaust gas into the reduction zone elevates the high-temperature flame region to some extent

which is beneficial for maintaining steam parameters during deep flexible peak regulation

yielding superior coordinated performance for both lowload stable combustion and flue gas temperature regulation. Through numerical analysis

the coordinated control strategy for achieving stable combustion at low loads and regulating flue gas temperature through the reuse of primary air exhaust gas is determined. The study results can provide a basis for the low-load operation of this type of coal-fired boiler during deep peak shaving.
