Novel low-nitrogen long-flame combustor

Abstract

The invention discloses a novel low-nitrogen long-flame combustor which comprises a combustor body and a control cabinet, the combustor body is connected with a control base in a bolt mode, a combustion chamber is arranged in the combustor body, a combustion head is arranged at the front end of the combustion chamber, and a mixing pressurization cavity is fixedly formed in the end, away from the combustion head, of the combustor body. The mixing pressurization cavity is fixedly connected with a front branch pipeline located on the combustor body, a waste heat gas circulating pipe is fixedly arranged on one side of the combustor body, a gas relief valve and a fuel gas pressure gauge with a pressing type valve are fixedly installed on the front branch pipeline, and a filter is installed at the position of a port of the front branch pipeline. According to the novel low-nitrogen long-flame combustor, the effective low-nitrogen combustion effect is achieved, the flame temperature is greatly increased, NOx emission of a combustion furnace applying the low-nitrogen combustor is reduced, meanwhile, early-stage fuel gas dust can be effectively filtered, and meanwhile the requirements for fuel gas pressure adjustment and pressure stabilization are met.

Description

technical field [0001] The invention relates to the technical field of combustion equipment, in particular to a novel burner with low nitrogen and long flame. Background technique [0002] Existing burners have problems such as low degree of automation and environmental pollution. With the increasingly stringent requirements of the country for environmental protection, energy saving and emission reduction, the existing low-nitrogen burner fuel and air are not mixed enough, so that the mixed fuel will burn after ignition. Incomplete, a large amount of NOX and CO and other gases are produced, and part of the discharged gas is combustible, resulting in waste of resources and pollution to the environment. The original burners did not consider the impact of the flame injection state on work. The impact of the original burner, and the adjustment of the height according to the ground conditions when the original burner is docked outdoors is laborious, especially when it is fixed in...

Problems solved by technology

[0002] Existing burners have problems such as low degree of automation and environmental pollution. With the increasingly stringent requirements of the country for environmental protection, energy saving and emission reduction, the existing low-nitrogen burner fuel and air are not mixed enough, so that the mixed fuel will burn after ignition. Incomplete, a large amount of NOX and CO and other gases are produced, and part of the discharged gas is combustible, resulting in waste of resources and pollution to the environment. The original burners did not consider the impact of the flame injection state on work. The impact of the original burner, and the adjustment of the height according to the ground conditions when the original burner is docked outdoors is laborious, especially when it is fixed in the kiln, it is not easy to move. The control of the whole cannot be realized, and most burners cannot filter the gas selection. In order to ensure the normal operation of the burner and achieve the effect of low nitrogen and long flame, the applicant specially designed a new type of burner. To meet the needs of industrial use
