Further, the air inlet end of the pilot tube 11 is provided with a blower (not shown in the figure) for allowing combustion air required for combustion to enter the flame path 3.

Further, the heat radiation layer 6 is disposed on the outer wall of the heat-resistant air guiding column 2 and/or the inner wall of the burner housing 1, and the heat radiation layer 6 is disposed on the outer wall of the heat-resistant air guiding column 2 and the inner wall of the burner housing 1 in this embodiment, and the heat generated by the heat radiation layer 6 can increase the combustion reaction speed and the combustion reaction temperature in the flame path 3, so that the flame path enters a high-speed combustion state more quickly.

Further, the projection surface of the heat-resistant air guide column 2 and the projection surface of the inner cavity of the burner housing 1 are circular, the heat-resistant air guide column 2 is arranged at the bottom center position of the burner housing 1 to form a circular flame path 3, the ignition tube 11 of the heat-resistant air guide column 2 is arranged in the tangential direction of the flame path 3, and the circular flame path 3 is matched with the ignition tube 11 in the tangential direction of the circular flame path, so that the diffusion of flame during the preheating stage can be facilitated, atomized liquid diesel can be quickly vaporized, and the combustion effect can be improved.

Further, the heat radiation arc surface 21 is arranged at the position of the top of the heat-resistant air guide column 2 corresponding to the flue gas outlet 12, so that the surface area of the heat radiation layer 6 of the heat-resistant air guide column 2 is increased, and the heat transfer effect is improved.

The working principle and the working process of the application are as follows:

firstly, under the action of a blower, air required by combustion enters a flame path 3, meanwhile, diesel oil is sprayed to the flame path 3 under the action of an atomization nozzle 41 to form a spray cone of diesel oil liquid particles, an ignition needle 5 discharges, and the diesel oil liquid particles are ignited and burnt;

the diesel particles after ignition will burn in a diffusion combustion mode, along with combustion air, enter the annular flame path 3 from the ignition tube 11, flame produced by combustion burns along the annular flame path 3, and will fill up the whole space of the annular flame path 3, the liquid diesel particles near the flame and flame root meet and heat, at this moment, some liquid diesel particles will be vaporized before completely burning in liquid form, thus begin burning in the form of diesel steam, because the volume can increase hundreds of times after the liquid diesel particles are vaporized, the contact area with combustion air will also increase greatly, thus make the combustion reaction temperature in the flame path 3 rise rapidly, meanwhile, the temperature of the combustion air also rises greatly, further raise the combustion reaction temperature, in the mutual promoting cycle, the flame temperature will rise rapidly;

in the initial stage of ignition combustion, the flame temperature is lower due to the slower speed of the combustion reaction, so that the distance required for complete combustion of diesel is longer, the formed flame is longer, the whole flame path 3 is generally filled, the flame is shorter and shorter along with the enhancement of the combustion reaction and the rise of the flame temperature, the flame can be burnt out after a plurality of circles from the beginning, the length of the flame is continuously reduced, but the temperature in the flame path 3 is continuously increased;

then, when atomized diesel oil liquid particles are injected into the high-temperature flame path 3 from the tangential direction of the rotating flame path 3 in the form of an injection cone, due to the high ambient temperature, a liquid explosion phenomenon is generated, wherein the liquid explosion phenomenon refers to an explosion phenomenon generated by instantaneous vaporization of the diesel oil liquid particles in the high-temperature environment (similar to the explosion phenomenon generated by water drops when the water drops fall into high-temperature oil in life), and the liquid explosion phenomenon can be understood by a person skilled in the art to further strengthen the combustion reaction and enter a high-speed combustion stage;

because the high-speed combustion has a very fast combustion speed, the time required for completing the combustion reaction is short, the required space is also small, the flame generated by the combustion reaction is very short, the flameless combustion effect can be realized, the products of the high-speed combustion of diesel can be thoroughly cleaned, even if the excess air coefficient is very small, the high-speed combustion has good combustion conditions under the condition that the content of the excess oxygen in the flue gas is close to zero, the content of harmful gases such as CO in the flue gas is very low, the content of the harmful gases in the flue gas is generally close to zero under the normal condition, the phenomena such as incomplete combustion, carbon precipitation and the like are not generated in the normal use process, and the emission index of the high-speed combustion of diesel is far superior to that of natural gas and liquefied gas, so the diesel can become a clean energy source after the high-speed combustion technology of diesel is used.

The above examples are only preferred embodiments of the application, and other embodiments of the application are possible. Equivalent modifications and substitutions can be made by those skilled in the art without departing from the spirit of the application, and these equivalent modifications or substitutions are intended to be included within the scope of the present application as set forth in the following claims.
