| الوصف: | [Introduction] In order to solve the problems of poor stable combustion, unstable hydrodynamics, and too low SCR inlet flue gas temperature during the deep peak shaving process of power station boilers, it is imperative to reform the boiler to stabilize combustion. [Method] In this paper, taking the flexibility transformation of a 660 MW thermal power unit boiler as an example, two effective stable combustion transformation schemes were proposed, and the effects of the combustion and pulverizing system transformation on the furnace and NOx emissions were analyzed. [Result] Both retrofit schemes can improve the ultra-low load and stable combustion characteristics of the boiler. The retrofit of the combustion and pulverizing system has little impact on the furnace and NOx emissions and is comparable in terms of technical reliability, construction difficulty, and workload. In contrast, scheme 1 is slightly better. [Conclusion] The two transformation schemes have been theoretically verified and feasible, and can provide technical reference for flexible transformation of the same type of units. |
