Wall-mounted furnace heating is one of the main ways of winter heating in northern rural areas. Due to the pressure fluctuation of the gas pipeline, the wall-mounted furnace is prone to combustion instability, and even CO poisoning accidents. In order to reveal the variation law of temperature field and combustion products in gas-fired wall-mounted furnace under the change of pipeline pressure, taking the fire row burner as the research object, the distribution of gas composition at the outlet of the ejector device, the temperature in the combustion chamber, and the concentration of CO and NO in the flue gas at the outlet of the combustion chamber under different pipeline pressures were studied by numerical simulation and experiment. The results show that. ① With the decrease of the gas inlet pressure, the methane concentration at the outlet of the fire increases, and the non-uniformity of methane concentration increases. ② As the gas inlet pressure decreases, the CO mass concentration at the outlet of the combustion chamber gradually increases. When the gas inlet pressure is 500 Pa, the CO mass concentration reaches a peak of 25.2 mg/m3, which is higher than the human body CO poisoning accident limit of 23 mg/m3. The mass concentration of NO at the outlet of the combustion chamber increases first and then decreases, reaching a peak of 18.99 mg/m3 at 1 500 Pa. ③ As the gas inlet pressure decreases, the maximum temperature in the combustion chamber increases first and then decreases. The minimum temperature is 1 840 K at 500 Pa. The combustion is not sufficient and the heat generated by combustion is less. It can be seen that the decrease of the pipeline pressure increases the instability of the wall-mounted furnace combustion and the CO concentration also increases significantly. The results can provide some theoretical support for the manufacturers of gas wall-mounted furnaces in enhancing the safety of equipment.

3,高于人体CO中毒事故限值23 mg/m
3;燃烧室出口处NO质量浓度呈先增加后减少的趋势,在1 500 Pa时达到峰值为18.99 mg/m
3;③随着燃气入口压力减小,燃烧室内最高温度先增加后减小,在500 Pa时温度最低为1 840 K,燃烧不充分,燃烧生成的热量少;可见,管网压力变小使壁挂炉燃烧的不稳定性增加且CO浓度也显著变大。本文研究结果可为燃气壁挂炉生产厂家在增强设备安全性方面提供一定的理论支持。, correspAuthors=纪运广, authorNote=null, correspAuthorsNote=
