摘要: 为提升燃气热水器的火排性能,采用数值模拟的方法对火排内部流场和浓度场进行了仿真计算,探究了火排焰孔深度的影响,分析得出焰孔深度的增大能有效解决火孔气流倾斜的问题,且能够改变火孔出口气流速度大小与均匀性,但对火孔出口甲烷浓度均匀性的影响不大,为燃气热水器中火排的设计提供了参考。

Abstract: To enhance the flame array performance of gas water heaters, the numerical simulation method was used to simulate the internal flow field and concentration field within the flame array. The influence of flame array orifice depth was investigated. The analysis indicates that increasing the orifice depth effectively resolves the issue of airflow deflection at the flame ports, alters the magnitude and uniformity of airflow velocity at the orifice outlets, yet has minimal impact on the uniformity of methane concentration at the flame port exits. This provides valuable reference for the design of flame arrays in gas water heaters.
