The utility model discloses a new high-efficiency gas wall-hanging furnace burner, which comprises a burner head and a combustion mixing chamber, in which the burner head is located above the combustion mixing chamber, and the burner head is connected with the combustion mixing chamber; the burner head is provided with a combustion fire exhaust arranged by several fire holes groups; each fire hole group is respectively provided with a rectangular fire hole and a rectangular fire hole. The combustion mixing chamber consists of a contraction section, a throat, a mixing section and a diffuser section, in which the contraction section is connected with the throat, the throat is connected with the mixing section, the mixing section is connected with the diffuser section, and the diffuser section is connected with the head of the burner. On the basis of the original combustion exhaust, the overall shape size of the utility model remains unchanged. By changing the size of the key parts of the exhaust and the shape of the fire hole, the combustion condition is better improved, the combustion stability is higher, the safety is higher, the rated heat input is further increased, and the combustion emission is low, and the CO emission content in the flue gas is greatly reduced.

技术介绍
燃气热水设备,如燃气热水器或燃气锅炉中通常设置有的燃烧器、热交换器、以及容纳燃烧器和热交换器的燃烧室。燃烧器往往包括有并排设置的若干火排片,每一个火排片具有燃气-空气的混合通道,可在其内将燃气和空气混合并传递给位于火排片顶部的火孔以在燃烧室内燃烧并生成热量,生成后的热量可加热热交换器内的水,从而被加热的水可用于饮用、洗浴、或供暖等。燃气采暖炉以天然气为燃料(主要成份为CH4),在燃烧过程中,CH4燃尽需6级反应才能完成,由于外界的影响可能出现反应中间过程终止,导致不完全燃烧产物出现。尤其是在最后反应阶段,若不能完全进行,将引起烟气中CO排放量上升,甚至超标。烟气中的CO含量必须严格限制,而CO的含量不仅可以衡量燃气燃烧是否完全,还可以评价燃烧产物的污染程度,燃气采暖壁挂炉正常运行时,出现的回火、脱火、黄焰现象都会引起CO含量增大以及燃烧安全性,而产生CO的关键跟燃烧火排的结构设计有很大关系。另外在安全方面考虑,燃烧火焰的稳定性以及燃烧的热效率都与燃烧火排有关 ...
