Gas velocity degree, unit air inflow, to obtain the mixing ratio of preferable combustion gas and air, guarantee combustion gas by sufficiently effective burning,
Reduce exhaust gas discharge.
In alternative embodiment, control aerofoil 30 has the first air regulating port 31 being oppositely arranged with air inlet 112, the first air regulating port
31 circulation area is less than the circulation area of air inlet 112.In this way, can effectively improve into the wind pressure in premix chamber 111, mention
The flowing velocity of high gas flow is sufficiently mixed combustion gas and air in premix chamber 111, to guarantee that combustion gas is filled
Divide effective burning, reduces exhaust gas discharge.
Wherein, the center spacing of two neighboring first air regulating port 31 is at a distance from the center line of two neighboring fire row monomer 11
It can be equal.It is imported in premix chamber 111 thus, it is possible to be more conducive to gas.
In further alternative embodiment, as shown in figure 4, premix chamber 111 includes: horizontal extension section 1111 and upwardly extends section
1112, horizontal extension section 1111 and upwardly extend between section 1112 have turning section 1113, the circulation area of turning section 1113 with
Total circulation area of first air regulating port 31 is identical.In other words, control aerofoil 30 on all first air regulating ports 31 circulation area with turn
The circulation area of curved segment 1113 is identical.In other words, in the entire flowing stroke of combustion gas and air, the circulation area of gas is presented
Multiple mutation guarantees that combustion gas by sufficiently effective burning, is reduced to be further ensured that combustion gas and air are sufficiently mixed
Exhaust gas discharge.
In optional implementation example, one end of control aerofoil 30 is equipped with baffle 32, and the fitting of baffle 32 is set on fire row monomer 11,
For covering the input end of the plenum duct 20 of neighbouring 112 side of air inlet.In this way, plenum duct 20 and premix chamber can be prevented
Gas in 111 channels is mutually collaborated.
In other embodiments of the utility model, burner 10 further include: shield 40.Shield 40 is located at fire row list
For controlling the air inlet entered in plenum duct 20 on body 11.In other words, entered in plenum duct 20 by the control of shield 40
Unit intake velocity, unit air inflow.
In alternative embodiment, 40 part of shield has the second air regulating port 41 communicated with plenum duct 20.I.e. by the
Two air regulating ports 41 are closed to 20 local relief of plenum duct, the shielded plate 40 of remaining input end of plenum duct 20.In other words, it fires
Burner 10 can control total air capacity by shield 40, so that the mixing ratio of preferable combustion gas and air is obtained, so that combustion
Gas is sufficiently burned.
In other embodiments of the utility model, the top of each fire row monomer 11 is set adjacent to the position of fire hole 113
There is the fiery piece 116 of biography, the biography fire piece 116 of two neighboring fire row monomer 11 is oppositely arranged.
In alternative embodiment, as shown in Figure 5 and Figure 6, fire row monomer 11 include: first around plate 114 and second around plate
115.First, which is connected with each other simultaneously structure around plate 115 around plate 114 and second, sets out premix chamber 111.Wherein, first plate 114 is surrounded
Surrounding plate 115 with second can be sheet metal component.
In optional example, as shown in figure 5, passing fiery piece 116 is located at first around the top that plate 114 and second surround and under
