四角切圆水平浓淡锅炉炉膛数值模拟对比分析

Analysis by numerical simulation of the horizontal bias burner of four corner tangentially fired boiler

本文采用数值计算方法分析在四角切圆水平浓淡煤粉燃烧器结构下煤粉锅炉的炉内流动特性。采用Fluent软件得到不同工况的对比结果。本文对水平浓淡煤粉燃烧器的改造优化提出了参考建议。

Numerical calculation was adopted on a four comer tangentially fired boiler to analysis flow characteristics under different structure of horizontal bias burner. It uses Fluent software to calculate the characteristics of flow under different case. This paper has a reference suggestion on the optimization and rebuild of horizontal bias burner.
