Fuel enters through the fuel tedge of double end fuel gun, be divided into two parts, a part is sprayed by the first fuel gun head be positioned at inside quirk brick, in the inner chamber combustion of quirk brick, another part is sprayed by the second fuel gun head be positioned at outside quirk brick, directly sprays into the upper area burning of stove internal-quirk brick.Double end fuel gun makes fuel divide two parts to enter burner, achieves the classification of fuel, and the fuel of classification completes burning in two relatively independent combustion zones, has excessive air in combustion.The fuel sprayed by the first fuel gun head is in the internal-combustion of quirk brick, and fuel is at excessive combustion synthesis in air, and a large amount of air can reduce the temperature of flame kernel, thus avoids oxynitrides NO
xa large amount of productions; The upper area that the fuel sprayed by the second fuel gun head directly sprays into stove internal-quirk brick burns, the time participating in burning due to this part fuel relatively lags behind, and flame front is widened, and avoids flame and concentrates, significantly reduce flame kernel temperature, thus reduce oxynitrides NO
xa large amount of generations.
In the present embodiment, the cross section of described burner can be circular.The quirk brick 1 with inner chamber is positioned at burner shell 3, is provided with furnace bottom lining 6 outside quirk brick.
There is combustion air passage in burner shell 3, burner shell 3 is provided with the wind passage mouth 4 be connected with air adjustment actuator, wind passage mouth 4 communicates with combustion air passage, combustion air passage communicates with the inner chamber of described quirk brick, thus air can be passed into by air adjustment actuator to as in the inner chamber of fire trough, to ensure the Thorough combustion of fuel.
Between described quirk brick 1 and described burner shell 3, thermal insulation layer or puigging can be set.Make the temperature of burner shell outer wall unlikely too high, play the object reducing noise simultaneously.
Described quirk brick 1 can be cylindrical, altar lamp 2 can be set at the correct position of the inner chamber of described quirk brick, the central axis place of the inner chamber of quirk brick is provided with fringe flame device 9, the adjustable flowing being entered the air in inner chamber by combustion air passage of fringe flame device 9, make to be distributed in the first fuel gun head ambient air evenly, make fuel combustion more abundant, combustion flame is more stable.
The number of double end fuel gun is that M, M are integer and M >=3.Double end fuel gun is around described quirk brick 1, and described first fuel gun head is positioned at the inner side of quirk brick, and the second fuel gun head is positioned at the outside of described quirk brick, is provided with the passage passed for the second fuel gun head at the outer wall of quirk brick.The structural representation of the quirk brick of a kind of burner provided for the present embodiment see Fig. 2, Fig. 2.
A kind of burner that the another embodiment of the utility model provides, see Fig. 1, comprises quirk brick 1, multiple double end fuel gun and burner shell 3.
Described quirk brick 1 is positioned at described burner shell 3, and described quirk brick 1 has the inner chamber as fire trough.
