Abstract

The invention relates to a low nitrogen oxide burner and a gas water heater. The low nitrogen oxide burner comprises a body, wherein the body is provided with an injection channel, a rich flame flow dividing part, a lean flame flow dividing channel, a lean flame mixing cavity and two rich flame mixing cavities formed on two sides of the lean flame mixing cavity respectively. According to the invention, the nitrogen oxide emission can be effectively reduced. Due to the fact that only one injection channel is adopted, and only one gas nozzle needs to be used in specific use, the reliability is high compared with the adoption of multiple injection channels and multiple corresponding gas nozzles.

Description

technical field [0001] The invention relates to the technical field of burners, in particular to a low nitrogen oxide burner and a gas water heater. Background technique [0002] In the field of gas water heaters, the current major gas water heater manufacturers only reduce CO emissions, and have not paid enough attention to low nitrogen oxide emissions. In the traditional burner technology, most of them are ordinary atmospheric burners, NO X Gas (nitrogen oxides) emissions are high, which is not conducive to low-nitrogen environmental protection emission requirements. At present, there are burners using rich-lean combustion technology in the industry to achieve low nitrogen oxide emissions. However, the traditional burner has dual injection channels and a relatively complex structure, which brings many challenges to the manufacturing process, circuit program control, and product performance stability. Contents of the invention [0003] The first technical problem solve...
