Abstract
The utility model discloses a low NOx of tertiary burning discharges nozzle, including the nozzle main part, be located the inside inner chamber of nozzle main part, installation including the combustion chamber, the sky of being connected with the combustion chamber of intracavity fire the mixing head, inner chamber and air conduit intercommunication, the sky fires the mixing head and is connected with a gas pipeline and an air inlet, the opening part of combustion chamber is equipped with the 2nd air inlet, the 2nd air inlet's the outside is equipped with the 3rd air inlet. Few partial air advanced an air inlet and got into empty firing in the mixing head, burn in the combustion chamber with the gas mix, this moment is for once burning, gas after the burning through the blowout of combustion chamber opening and with burn by the 2nd air inlet incoming air, form postcombustion, continue forward the gas mixture blowout back that postcombustion formed, air mixing with the entering of the 3rd air inlet, form the cubic burning in the stove, multistage combustion technology can effectual reduction flame combustion temperature, greatly reduce the NOx who produces among the combustion processes.
Description
Technical field
The utility model relates to a kind of multistage combustion burner, is specifically related to a kind of three grades of burning low NOx drainage burners.
Background technology
Nitrogen oxides all has toxicity in various degree.Nitrogen oxides is the principal element that acid rain is formed, and one of is three big reasons of haze formation.Current domestic each big and medium-sized cities all endure the invasion of haze to the fullest extent, and it is healthy that environmental pollution has badly influenced the production of people, life and life security.Along with the attention of domestic environmental pollution, and the requirement to industrial furnace NOx emission is increasingly stricter, how to effectively reduce the NOx that burner produces in combustion and has become a difficult problem.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provide a kind of scientific and reasonable for structure, can effectively reduce three grades of the NOx produced in combustion burning low NOx drainage burners.
The utility model solves its technical problem and be the technical scheme is that
A kind of three grades of burning low NOx drainage burners, the air-fuel mixing head that the inner chamber including burner main body, being positioned at burner body interior, the combustion chamber being arranged on inner chamber are connected with combustion chamber, described inner chamber connects with air duct, described air-fuel mixing head connects gas pipeline and the first air intake, the opening part of described combustion chamber is provided with the second air intake, and the outside of described second air intake is provided with the 3rd air intake.
In the utility model, being additionally provided with ignitor in described combustion chamber, described ignitor is connected in burner main body and extends in air-fuel mixing head.
In the utility model, described combustion chamber is ceramic-lined chamber.
In the utility model, described burner main body includes being located at the burner shell that the burner block outside combustion chamber is connected with burner block, passes through Flange joint between described burner block and burner shell.
In the utility model, the internal diameter of described combustion chamber is gradually reduced along opening direction.
The beneficial effects of the utility model are: small part air entered the first air intake and enters in air-fuel mixing head, with combustion gas mixing in burning Indoor Combustion, now for primary combustion, gas after burning is sprayed by combustion chamber openings and burns with the air entered by the second air intake, form second-time burning, continue forward after the gaseous mixture ejection that second-time burning is formed, the air entered with the 3rd air intake mixes, three burnings are formed in stove, multistage combustion technology can effectively reduce flame combustion temperature, greatly reduces the NOx produced in combustion process.
