Secondary ignition temperature rises and destruction stability, and this technical scheme can effectively improve the thermal efficiency, save the energy, reduce in burning
The generation of oxynitrides, still, the structure of burner still seem complicated, and burner relies on natural environment cooling, and effect is not
It is very significantly, to be worked under the long-time condition of high temperature, it is impossible to oxynitride discharge is effectively greatly lowered.
Chinese patent：2015203675352 disclose the burner for wall-hung boiler, and main technical schemes are：If setting
Dry fire row arranged side by side, the both sides up and down of each fire row, which are respectively equipped with the fin on the upside of fin, fire row, to be respectively equipped with together
The lower radiating mounting hole of coaxial line is respectively equipped with the upper radiating mounting hole of axis, the fin of downside, on radiating mounting hole
Provided with circulating water pipe, the effect of radiating and fast cooling is improved by increasing the circulating water pipe in fin, and fin,
Reduce the generation of oxynitrides；This technical scheme, is, by the fin in circulating water fire row, then to pass through fin
Indirectly and fire row carry out it is cold and hot exchange, to reach cooling and reduce the effect discharged, but equally exist complicated, volume is swollen
Greatly, the problem of manufacturing cost is high；In order to solve the above problems, it is proposed that a kind of water cooling low NO, it has ignition temperature
It is low, the few advantage of oxynitride discharge.
