The present invention discloses a
hydrogen stable
combustion ammonia burner, the structure from the center to the outside includes a coaxially arranged first-stage
hydrogen spray gun, a first-stage
cyclone, a first-stage
ammonia spray gun, a second-stage
cyclone, a second-stage
hydrogen spray gun, a second-stage
ammonia spray gun, a
direct current wind interlayer, a third-stage hydrogen spray gun, and a third-stage ammonia spray gun.
Ammonia and hydrogen enter the
ammonia gas collecting ring and the hydrogen gas collecting ring respectively, and each fuel realizes three-stage fuel classification through spray guns designed at different radial positions; wherein, the second-stage hydrogen spray gun and the second-stage ammonia spray gun are arranged alternately in the second-stage
cyclone; the third-stage hydrogen spray gun and the third-stage ammonia spray gun are arranged in a coaxial sleeve type. The
combustion-supporting wind enters from the
combustion-supporting wind inlet, and is divided into three stages through the first-stage cyclone, the second-stage cyclone, and the
direct current wind interlayer, wherein the first-stage cyclone is a strong cyclone, and the second-stage cyclone is a weak cyclone. The present invention uses ammonia as the main fuel and hydrogen as the auxiliary fuel, and performs
staged combustion and stage-by-stage stable combustion, thereby improving the stability and
burnout of ammonia combustion and reducing
nitrogen oxide emissions.
