摘　　要：针对部分壁挂炉夏季出水太烫的问题,采用宽裕负荷比的分段燃烧技术拓宽壁挂炉负荷输出范围,提高其适应不同负荷需求的能力,避免夏季水温过烫问题。采用理论计算与试验测试结合的方式对分段燃烧器关键参数进行确定,并装机上台完成性能测试。结果表明:相比大气式壁挂炉,分段燃烧的壁挂炉在不影响最高热负荷输出的基础上,最小热负荷值向下拓宽了60%,低至4.0 kW,小火排负荷输出能有效解决因负荷输出过大造成水温太烫问题,提高用户用水舒适体验感。To solve the problem of excessive water temperature in summer,the segmented combustion technology with a generous load ratio is used to widen the load output range of the wall-hung boilers,improve their ability to adapt to different load requirements and avoid the occurrence of excessive water temperatures in summer.The key parameters of the sectional burner are determined using a combination of theoretical calculations and experimental tests,and the performance tests are completed on the installation stage.The results show that:compared to atmospheric wallhung boilers,the minimum heat load value of the sectional burner is widened by 60%downwards to 4.0 kW without affecting the maximum heat load output,and the small fire row load output can effectively solve the problem of water temperature being too hot due to excessive load output and improve the user's comfort experience with water.
