Abstract
The utility model discloses a low nitrogen oxides and flame adjustable burner nozzle, belonging to the technical field of a burner. The utility model is composed of a peephole, a gas pipe, a gas distributing plate, an air inlet pipe, an air control valve, a burner nozzle tile, and an ignition hole. The center of the burner nozzle is provided with a center air pipe. The air inlet pipe is divided into two channels for feeding the air through the air control valve, the interior of one air channel is provided with an air swirler, and the other air channel are a plurality of channels which are not uniformly arranged on the circumference of the burner nozzle tile. The utility model has the advantages of convenient burning regulation, and low generation quantity of the nitric oxide.
Description
The utility model belongs to technical field of burner, relates in particular to a kind of low Nox coal gas and transfers flame burner nozzle.
Along with the raising of people to the environment attention degree, people have also proposed corresponding requirement to the content of nitrogen oxide in the burner combustion flue gas.Existing coal gas is transferred flame burner nozzle, is made up of peep-hole, Gas Pipe, coal gas distribution plate, air intake duct, air control valve, burner block, fire hole etc.The deficiency of its existence is: no center wind is taken over, and makes the adjusting ratio of burner be difficult to guarantee; The regulating power of air control valve is relatively poor, makes the mixing condition of sky, coal gas wayward, makes burning localized hyperthermia occur easily, thereby makes that the content of nitrogen oxide in the combustion product gases is quite high.
The purpose of this utility model is to provide a kind of low Nox coal gas to transfer flame burner nozzle, and this burner combustion is easy to adjust, reduces the growing amount of nitrogen oxide.
The purpose of this utility model realizes as follows: low Nox coal gas transfers flame burner nozzle to be made up of peep-hole, gas pipe, coal gas distribution plate, air intake duct, air control valve, burner block, fire hole, at the burner center one central air hose is installed; Air intake duct divides two passes air-supplied through air control valve, in the air duct air cyclone is installed, and another air duct is a plurality of inhomogeneous passages that are arranged on the burner block circumference.
Effect of the present utility model:, make burner have bigger adjusting ratio and good flame holding because burner is provided with central air hose; Air infeeds at twice, and primary air infeeds with coal gas through the air cyclone rotation and mixes; Auxiliary air directly infeeds through burner block, and by changing the position of air control valve, the mixed proportion of regulating first and second air and coal gas reaches and controls burning condition empty, coal gas, avoids occurring burning localized hyperthermia, reaches the growing amount that reduces nitrogen oxide.
Below in conjunction with accompanying drawing enforcement of the present utility model is described further.
Fig. 1 structural representation of the present utility model
Fig. 2 A-A cutaway view of the present utility model
Among the figure, part 1 is a peephole, and part 2 is a central air hose, and part 3 is a gas pipe, and part 4 is an air intake duct, and part 5 is an air control valve, and part 6 is an air cyclone, and part 7 is the coal gas distribution plate, and part 8 is a burner block, and part 9 is a fire hole, and θ is that the angle is expanded in the burner block outlet.
As shown in the figure, low Nox coal gas transfers flame burner nozzle to be made up of peep-hole 1, gas pipe 3, coal gas distribution plate 7, air intake duct 4, air control valve 5, burner block 8, fire hole 9, and a central air hose 2 is installed at the burner center; Air intake duct 4 is air-supplied through 5 fens two passes of air control valve, in the air duct air cyclone 6 is installed, and another air duct is a plurality of inhomogeneous passages that are arranged on the burner block circumference.It is 20～50 ° that angle θ is expanded in the burner block outlet, and it is 40 ° that angle θ is expanded in the outlet of present embodiment burner block.Air is entered by air intake duct 4, infeed at twice through air control valve 5, primary air infeeds through air cyclone 6, auxiliary air infeeds through burner block 8, coal gas is infeeded through coal gas distribution plate 7 by gas pipe 3 and mixes with air, mist burns while flowing along the burner axis direction, by changing the position of air control valve 5, adjusting one, two air mix with coal gas, reach the burning condition of control sky, coal gas, avoid occurring burning localized hyperthermia, reach the growing amount that reduces nitrogen oxide.
