摘要
本文研究在不同工况下某660MW墙式切圆煤粉锅炉的炉内燃烧特性。使用ICEM CFD建立模型,通过Fluent14.0用数值模拟的方法研究不同燃烧器摆动下的燃烧特性和流动特性。动力学参数经过试验确定,并且通过现有工况验证,以此来得到炉内的研究结果:速度场、烟气温度等。本文对墙式切圆煤粉炉燃烧器的优化改造起到了一定的指导作用。
Numerical simulation was conducted on a 660MW boiler with wall arrangement burners to investigate combustion characteristics under different conditions. This paper use ICEM CFD to found model and Fluent 14.0 to simulate the characteristics of combustion and flow under different swing levels. These kinetic parameters are ensured by examination to get the result, such as velocity field, the temperature of flue gas. This paper have an instructional influence on optimize of boiler with wall arrangement burners.
