Double-high burner

本发明涉及一种双高燃烧器，它包括供气部分、燃料供给部分及汽化加热燃烧部分三个部分。与现有的燃烧器相比具有如下优点：1.将空气加热成高温空气后与高温燃气混合燃烧，燃烧可在低氧条件下进行，燃烧温度高，燃烧稳定，炉膛内火焰无温度峰值，无火焰界面，炉膛温差小，炉膛平均温度高，烟气温度低，热效率高，CO和NO#-[x]含量低。燃烧充分，既保护了环境又节约了能源；2.将预热汽化室置于燃烧器外侧，可减少加热汽化过程中的热量损耗，增加加热汽化面积，提高了燃气温度；3.采用多级汽化加热结构，逐级加热汽化，增加了气体行程，汽化加热速度更均衡、稳定，燃气温度高；4.输油管是由上部开有向四周喷射的小孔、燃料进入预热汽化室得到均匀分散，使制控与受控同步，受控范围大，具有更好的适用性。 The present invention relates to a double-high combustor, including three portions of air supplying portion, fuel supplying portion and varporization heating and combustion portion. As compared with existent combustor said invention possesses the following advantages: heating air to obtain high-temp. air mixing the high-temp. air with high-temp. gas to make mixed combustion, combustion temp. is high, combustion is stable, combustion is full and high in thermal efficiency, CO and NOx contents are low, its preheating vaporization chamber is placed outside of combustor, it can reduce heat quantity loss, and can increase heating varporization area, and its gas temp. is raised, so that it possesses good service ability.
