Specific embodiment
Below by specific embodiment, the technical solution of the utility model is described in further detail.
As shown in Figure 1-Figure 3, a kind of burning of energy-saving anti-freezing of a furnace natural gas combustion nozzle, including the mixing chamber 1, top of lower section
The igniter 5 that room 2, the gas inlet 3 of connection mixing chamber 1 and combustion-supporting wind inlet 4 and respective combustion chamber 2 are set, combustion chamber 2
It is the narrow outlet of entrance conical tube wide, inlet diameter is 200mm, and outlet diameter is 320.
The outside of combustion chamber 2 sets the interlayer 6 of upper end open, and it is cylindrical shape body to form the shell 7 of interlayer 6, mixing chamber 1 and
The equal diameters of shell 7, are 400mm, and interlayer 6 closes up and set in the narrow back taper interlayer of internal outlet wide, the opening 8 of interlayer 6,
Close up a diameter of 350mm, and the width of interlayer opening 8 is 40mm, along the exit end face higher than combustion chamber 2 on the shell 7 of interlayer 6, folder
Outlet of the opening 8 of layer 6 around combustion chamber 2 is set to form the brattice around flame, and wind-guiding is installed at the opening 8 of interlayer 6
Plate/wind-guiding post 9, each wind deflector/wind-guiding post 9 is obliquely installed and is parallel to each other to make brattice in the shape of a spiral.
The bottom of interlayer sets air inlet 10, and a diameter of 100mm of air inlet 10, air inlet 10 is obliquely installed, incline direction
Incline direction with wind deflector/wind-guiding post 9 is consistent.
Observation window 11 is installed on the mixing chamber 1, it is convenient to observe air pressure inside, temperature and with the presence or absence of flame.
The course of work：Natural gas and air enter mixing chamber 1 according to a certain percentage, in combustion gas and air to sweeping away mixing
Uniformly, into combustion chamber 2, after igniter 5 first lights mixed gas, combustion continuation is carried out, due to the air-flow in mixing chamber 1
Impact, the combustion zone of combustion chamber 2 is located at beyond combustion chamber 2 so that gas and body of heater airflow in combustion chamber 2, and because
Combustion chamber 2 is flaring structure, it is to avoid fuel gas is detained in combustion chamber 2, safe.
Because combustion zone is located at outside combustion chamber 2, cause flame not constrain well, easily extend out, contact expansion furnace
12 furnace wall, causes freezing of a furnace.To solve this problem, to air is injected in interlayer 6, air is in folder for the air inlet 10 from interlayer 6
Eddy flow in layer 6, in the presence of wind deflector/wind-guiding post 9, forms and encloses brattice around the one of flame, and brattice effectively stops that flame connects
Touch furnace wall, it is to avoid freezing of a furnace, while flame boundling under the constraint of brattice, forms the column of flame, combustion zone is more concentrated, and is conducive to ore in sand form
Expansion.
Finally it should be noted that:Above example is only used to illustrate the technical solution of the utility model rather than it is limited
System；Although being described in detail to the utility model with reference to preferred embodiment, those of ordinary skill in the art should
