The utility model is compared with existing burner, has following advantage:
1. the multipole heating evaporation combustion device of Cai Yonging, or liquid is vaporized fully, and be heated to form high-temperature fuel gas, or make general gas be heated into high-temperature fuel gas step by step, and simultaneously air heat being become behind the high temperature air and high-temperature fuel gas mixed combustion, burning can be carried out under hypoxia condition, oxygen demand is little, ignition temperature height, flameholding, flame does not have temperature peak in the burner hearth, no flame interface, and burner hearth has a narrow range of temperature, burner hearth mean temperature height, flue-gas temperature is low, thermal efficiency height, CO and NO
xContent is low.Sufficient combustion has not only been protected environment but also saved the energy;
2. the preheating vaporizer is placed the burner outside, can reduce the thermal loss in the heating vaporescence, increase heating vaporization area, improved fuel gas temperature;
3. adopt preheating vaporization, elementary heating vaporization, secondary heating vaporization and high temperature to heat multistage vaporization heating arrangement, heating vaporization has step by step increased gas travel, and the vaporization firing rate is more balanced, stable, the fuel gas temperature height;
Petroleum pipeline be by top have to around the aperture, the fuel that spray enter the preheating vaporizer and evenly disperseed, make the system control with controlled synchronously, controlled area charactert is big, has better applicability.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of this device.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model double-high burner comprises air feed part, part of the fuel supply and three parts of vaporization heating flame part.
The structure of part of the fuel supply wherein is as follows: the end of open up claw-like fuel-supply pipe 8 is provided with the aperture 7 that sprays to all around, and purpose is that the liquid or the gaseous fuel that enter preheating vaporizer 5 are evenly distributed.The end peripheral seal of fuel-supply pipe 8 is equipped with preheating vaporizer 5, and the other end of fuel-supply pipe 8 merges after gauge tap 14 connects fuel tank; The carrier pipe 11 of boundling shape is to be that 120 ° tube bank constitutes by the angle between three tube and tube, and such structure can make fuel enter preheating vaporizer 5 equably;
