600MW旋流燃烧器燃烧过程数值模拟

Numerical Simulation on the combustion process of 600 MW swirl burner

本文研究在不同工况下某单只600 MW旋流燃烧器的炉内燃烧特性。使用Solidworks进行建模,通过Fluent15.0用数值模拟的方法,研究在不同内二次风旋流强度下的燃烧特点。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、烟气温度场等。本文对旋流燃烧对冲锅炉的运行工作起到了一定的指导作用。

Numerical simulation was conducted on a 600MW swirl burner to investigate combustion characteristics under different conditions. This paper use Solidworks to found model and Fluent 15.0 to simulate the combustion characteristics under different intensity of the cyclone swirling secondary air. These kinetic parameters are ensured by examination to get the result, such as velocity field, the temperature field of flue gas. This paper has an instructional influence on the running of Swirl - opposed Firing boiler.
