Abstract
The utility model relates to a flat flame environment protection burner which comprises fire path bricks of a peculiar design, a fuel air gun provided with a plurality of jet holes of different angles, a cylinder ensuring safe ignition of the fuel air gun, a burning pilot burner and a butterfly valve wind adjusting mechanism. The burner forms stable combustion supporting air through the wind adjusting mechanism of a special structure. The stable combustion supporting air thoroughly mixes with the fuel gas ejected by the fuel air gun to form flat flame. The dimension, the color and the temperature of the flame are controllable. The fuel gas is ejected by the air gun according to the different heights. The flame burns by stages, and the phenomena of flame concentrated on the high-temperature region is avoided. Thus, the flat flame environment protection burner has distinctive feature that the discharge amount of nitrogen oxides is lower than the discharge amount of the common burner. The fuel air gun of a special design is suitable to burn the gas. The flat flame environment protection burner can adopt natural ventilation and/or forced ventilation. The utility model is suitable to heaters of carbonization, etc. of the petrochemical industry.
Description
Technical field:
The utility model relates to the firing equipment field of petrochemical heating furnace, a kind of flat flame environmental protection burner.
Background technology:
At present, the round flame burner of the most of employing of the burner that domestic petroleum chemical industry heating furnace uses, the growing amount of nitrogen oxide is excessive; Though indivedual burners have adopted the measure of some control formation of nitrogen oxides, effect is all undesirable; Need flat flame burning device on some technology, but the shape of its flat flame does not reach designing requirement, cause the flame defective such as inhomogeneous of conducting heat.
Technology contents:
In order to overcome above-mentioned defective, the utility model provides a kind of flat flame environmental protection burner, makes it have the distinguishing feature that peak flame temperature is lower, the discharge capacity of nitrogen oxide is lower than the ordinary burner discharge capacity.
The utility model adopts following technical scheme to realize:
Flat flame environmental protection burner, by the quirk brick, the fuel air gun, cylindrical shell, altar lamp is transferred compositions such as wind mechanism, this burner top is equipped with the quirk brick of special shape, and this quirk brick is placed and formed inside is a square type groove, and the center is placed with the altar lamp that guarantees fuel air gun safety ignition, burning; Outside two of forming symmetry of quirk brick control the inclined-plane of mobile direction of fuel gas and angle; Quirk brick bottom is provided with a plurality of fuel air guns, and there is the different spray orifice of a plurality of blowing angles the rifle head position of fuel air gun; Butterfly valve transfers wind mechanism to be arranged on the cylindrical shell bottom, transfers the butterfly valve of wind mechanism to regulate the combustion air volume of flat flame environmental protection burner by this butterfly valve.
Owing to adopted above-mentioned technical scheme, the utlity model has following superiority: the utility model burner utilizes fuel air gun jet nozzle angle and quirk brick to place the reasonable coupling that forms the inclined-plane, and the flat flame that adheres to specification is provided; Adopt fractional combustion and flue gas recirculating technique to reduce the growing amount of nitrogen oxide, guarantee that flame conducts heat evenly, for the efficient operation of heating furnace device provides guarantee; Accent wind mechanism by special construction forms stable combustion air, and the abundant mixed combustion of fuel gas of spraying with the fuel air gun forms flat flame, and its flame size and color, temperature can be controlled; Have the distinguishing feature that peak flame temperature is lower, the discharge capacity of nitrogen oxide is lower than the ordinary burner discharge capacity, the growing amount that can control nitrogen oxide under normal operating condition is lower than 40ppm, and noise is reduced to below the 70DB (A), helps environmental protection; The fuel air gun of its particular design is applicable to the burning Device in Gas, can adopt gravity-flow ventilation and or forced ventilation.The utility model be applicable to petroleum chemical industry require combustion flame shaped flat, flame thermal radiation evenly, the unit furnaces such as coking of the little energy multi-combustor of low-nitrogen oxide discharging.
Description of drawings:
Fig. 1 is the structural profile schematic diagram of flat flame environmental protection burner;
Fig. 2 is the quirk brick side view of flat flame environmental protection gas burner;
Fig. 3 is the quirk brick vertical view of flat flame environmental protection gas burner.
Among the figure: 1-quirk brick, 2-fuel air gun, the 3-cylindrical shell, the 4-altar lamp, the 5-butterfly valve is transferred wind mechanism.
Specific embodiment:
As Figure 1-3, flat flame environmental protection gas burner is made up of quirk brick (1), fuel air gun (2), cylindrical shell (3), altar lamp (4), butterfly valve accent wind mechanism (5) etc.The quirk brick (1) of special shape is installed on this burner top, and this quirk brick (1) is placed and formed inside is a square type groove, and the center is placed with the altar lamp (4) that guarantees fuel air gun safety ignition, burning; Outside two of forming symmetry of quirk brick (1) control the inclined-plane of mobile direction of fuel gas and angle; Quirk brick (1) bottom is provided with a plurality of fuel air guns (2), and there is the different spray orifice of a plurality of blowing angles the rifle head position of fuel air gun (2); Butterfly valve transfers wind mechanism (5) to be arranged on cylindrical shell (3) bottom, regulates the combustion air volume of flat flame environmental protection burner by butterfly valve.The combustion air of certain blast or the natural air that is sucked by negative pressure in the stove are arranged, transfer wind mechanism (5) to regulate, enter quirk brick (1), enter with fuel gas through the quirk internal orifice and mix by cylindrical shell (3) through butterfly valve.Regulate the fuel gas that enters by control valve, after spraying by a plurality of spray orifice multi-angles of fuel air gun (2) rifle head, with air mixed combustion, form eddy current at red-hot quirk brick (1) outer surface, flue gas recycles.The mixed flue gas limit preheating of quirk brick (1) outer surface, the limit burning forms flat flame with the air mixing after-combustion that quirk brick (1) internal orifice enters at last.Because of fuel air gun (2) jet nozzle angle difference, the combustion gas spray angle of ejection is also different, form the recirculation effect of classification, sectional combustion and flue gas, suppressed the growing amount of nitrogen oxide, the growing amount that can control nitrogen oxide under normal operating condition is lower than 40ppm.Be provided with facilities such as filling up the noise elimination cotton in the porous plate in the cylindrical shell (3), the noise that burning produces can be reduced to below the 70DB (A).
Claims (1)
1, flat flame environmental protection burner, by the quirk brick, the fuel air gun, cylindrical shell, altar lamp is transferred compositions such as wind mechanism, and it is characterized in that: this burner top is equipped with the quirk brick (1) of special shape, this quirk brick (1) is placed and formed inside is a square type groove, and the center is placed with the altar lamp (4) that guarantees fuel air gun safety ignition, burning; Outside two of forming symmetry of quirk brick (1) control the inclined-plane of mobile direction of fuel gas and angle; Quirk brick (1) bottom is provided with a plurality of fuel air guns (2), and there is the different spray orifice of a plurality of blowing angles the rifle head position of fuel air gun (2); Butterfly valve transfers wind mechanism (5) to be arranged on cylindrical shell (3) bottom, transfers the butterfly valve of wind mechanism (5) to regulate the combustion air volume of flat flame environmental protection burner by this butterfly valve.
