Technical field
The utility model relates to gas industry stove technical field, is specifically related to a kind of Energy saving burning nozzle of the industrial furnace (comprising boiler) for operating on gaseous fuel.
Background technology
Its structure of fuel burner nozzle that existing industrial furnace is used mainly contains 3 parts and forms: 1, burner shell: major function is that burner is installed on body of heater, the installation site of burner is provided, and is provided with combustion air air inlet and is furnished with pressure tap---measure combustion air pressure etc.; 2, burner core: be mainly used to import combustion gas.Comprise that Gas Pipe (chamber), combustion gas governor motion, blade, flame ignition and flame monitoring mechanism, burner are first-class.On burner head, according to spraying mixing and blade etc., air is mixed with fuel gas; 3, burner block or burner pipe: as combustion chamber, applicable different fired states and installation requirement.
Oxygen rich gas combustion supporting technology is a new power-saving technology and theory.Oxygen rich gas refers to the gas that oxygen content is greater than 21%.Oxygen rich gas combustion supporting technology is a novel various Industrial Stoves power-saving technology of (comprising boiler) that is applicable to.Gaseous fuel application oxygen-enriched combustion-supporting can be given full play to the performance of fuel.Every in a broad sense all available oxygen enrichment replacements that participate in reaction with air.And oxygen rich gas must be carried out to structure of modification to existing industrial furnace relevant apparatus for industrial furnace.
Utility model content
The purpose of this utility model is to provide a kind of Energy saving burning nozzle, is the best approach of oxygen-enriched combustion-supporting when industrial furnace application oxygen rich gas is combustion-supporting in solution prior art.
The technical solution of the utility model is:
An Energy saving burning nozzle, comprises burner shell and burner core, and described burner core comprises burner head, mixes tube chamber and burner core afterbody; Wherein: the front end of described mixing tube chamber connects described burner head, burner core afterbody is stretched in the rear end of described mixing tube chamber; Described burner core afterbody is offered respectively and the gas inlet and the oxygen rich gas air inlet that mix tube chamber and be communicated with; Described burner shell is connected with described burner core afterbody and is arranged at and mixes tube chamber outside, on described burner shell, offers air inlet.
Described mixing tube chamber is straight tube or Venturi tube.
Described gas inlet, oxygen rich gas air inlet and air inlet are connected respectively gas inlet pipe, oxygen rich gas air inlet pipe and combustion air air inlet pipe.
The control valve that carries out flow-control is set respectively in described gas inlet pipe, oxygen rich gas air inlet pipe and combustion air air inlet pipe.
On described burner shell, can be connected with burner pipe.
The utility model is the device for industrial furnace by oxygen rich gas, fuel burner nozzle is partly oxygen rich gas pipeline to be connected in the combustion gas lumen tube on burner core on existing fuel burner nozzle primary structure basis, be that oxygen rich gas converges in Gas Pipe (chamber) with combustion gas before entering burner head, even if fuel gas mixes before entering burner head with the gaseous mixture of oxygen rich gas mutually.The advantage of this kind of nozzle structure is when needs add oxygen rich gas combustion-supporting to industrial furnace (comprising boiler), needn't transform the external stove gas pipeline of burner, combustion air pipeline, has avoided because of rebuilding construction complexity and safety problem.
The utility model beneficial effect is as follows:
1, the use of the utility model burner can effectively improve and guarantee the energy-saving effect of oxygen enrichment power-saving technology, and the stove that guarantees application oxygen enrichment power-saving technology is fuel saving not changing stove agent structure, do not change stove technique in the situation that; Can meet oxidizing atmosphere, neutral atmosphere or reducing atmosphere, adapt to the requirement of all kinds of gas burning kilns to combustion atmosphere.
2, the utility model is set up oxygen rich gas air inlet specially, and oxygen rich gas inlet port is built up in the burner afterbody of burner core, become one with burner combustion gas tube chamber, make oxygen rich gas and fuel gas synchronously enter the mixing tube chamber of burner core, and mix in straight tube or venturi tube chamber.Oxygen rich gas mixes the mixed effect that can improve mist with fuel gas in straight tube or venturi tube chamber, is conducive to promote that fuel combustion is complete, saves the energy.
3, adopt the utility model design, can guarantee oxygen-enriched combustion-supporting energy-saving effect.Oxygen rich gas inlet be theoretical combustion-supporting air quantity 10% in; Fuel saving, energy-saving effect reaches 10% left and right; Reduce smoke discharge amount, reduce nitrogen oxide and carbon monoxide thing discharge capacity.
