The specific embodiment
Embodiment
The fuel heater burner of multiple spot fuel feeding of the present utility model, its structure as shown in Figure 1.Comprise conical combustor lid 5, oil suction lining net 6, one-level combustion barrel 15, secondary firing tube 17, air inlet guide shell 14, air inlet spinning disk 12, fuel feeding straight tube 9, fuel feeding bend pipe 8, cloth oil inlet pipe 7, glow plug 18.Taper oil suction lining net 6 is close to the conical combustor interior surface, and the two is fixed as one by spot welding.The front end of one-level combustion barrel 15 inserts in the end positioning spigot of combustion chamber lid 5, oil suction lining net 6 is had the sturdy effect of pushing, and connect as one by welding and combustion chamber lid 5.Circumferentially be distributed with 2～5 several air admission holes 3 of circle on the barrel of one-level combustion barrel 15.One-level combustion barrel 15 is fixedlyed connected by spot welding with the tail end of air inlet guide shell 14, looping inlet chamber 13 between the two, and on the taper flange flange of the two, be distributed with 4～12 by-pass prots 16 that can reduce flow dead in the secondary firing tube 17.The two taper flange forms a reducing 1 that communicates with secondary firing tube 17, and secondary firing tube 17 is straight tubes that a front and back end is opened wide, and its front end sleeve is at the afterbody of air inlet guide shell 14, and is fixedly connected by circumferential welding.Air inlet spinning disk 12 is inserted in from the top of conical combustor lid 5, fits together with the flange ring flange of air inlet guide shell 14 front ends (inlet end), is evenly equipped with 10～20 air admission holes with spiral stream guidance leaf 11 on the air inlet spinning disk 12.Air inlet spinning disk 12 is provided with the sensor holder 4 that catches fire.Glow plug 18 inserts in the glow plug chamber 21 of combustion chamber lids 5 cone top parts, and is fixing by dog screw (or by pin, locking plate, jump ring and from threaded etc.).
The back side of conical combustor lid 5, fuel oil arrives cloth oil duct inlet 20 (referring to Fig. 2) through fuel feeding straight tube 9 and fuel feeding bend pipe 8, respectively fuel oil is sent to a plurality of on the inner surface of combustion chamber through cloth oil duct 21 and cloth oil inlet pipe 7 then and (arranged several according to the big I of inner surface, provide three in the present embodiment) cloth oilhole 24, and warp serves as a contrast net 6 adsorption and diffusion with the taper that the combustion chamber inner surface fits tightly.Cloth oil duct 21 is provided with fabrication hole, blocks by fabrication hole rivet 19.For being distributed, fuel oil more becomes even, as shown in Figure 3, inner surface design at conical combustor lid 5 has " eight " font spreader groove 25, the fuel oil of storing in the small rut around two the cloth oilholes in top can be uniform by lining net adsorption and diffusion on the way at its fuel oil in the dirty process of " eight " font oil groove, thereby it is long-pending to increase the cloth pasta, and it is more even that fuel oil is mixed with air.
The course of work of the present utility model is:
Be installed in this burner in the heater, after pressing the heater starting button, glow plug 18 is energized heating.When reaching scorching hot, fuel pump begins fuel feeding, the fuel oil that supplies enter in the burner through three cloth oilholes 24 of combustion chamber lid 5 inner surfaces, fuel oil flows into the oil suction lining net of combustion chamber lid inner surface through the cloth oilhole.In absorption and the diffusion fuel oil, have the part fuel oil to carry diffusion downwards through " eight " font oil groove 25 around the cloth oilhole of top, the cloth oilhole of bottom is responsible for to lower area cloth oil.The fuel oil that flows nearly glow plug 18 at first is heated the evaporation gasification, and mixes with the glow plug chamber 22 interior air that advanced by igniting airport 23.After reaching ignition temperature, gaseous mixture is burning immediately just, and this flame enters combustion chamber 2 rapidly, and is subjected to glow plug 18 bakings to evaporate the fuel oil of gasification around lighting oil suction lining net 6.By having the combustion air that tangential air hole 10 is advanced of jet action on the combustion chamber lid 5, near the inner surface of oil suction lining net 6, form swirling eddy.The oil gas that this swirling eddy purges on oil suction lining net 6 internal faces participates in mixing and burning.And, be blended into successively in the gaseous mixture of diffusion combustion of anoxic, thereby gaseous mixture is fully burnt by air inlet spinning disk 12, through the combustion air that annular inlet chamber 13, one-level combustion barrel air admission hole 3 enter in the combustion chamber 2.Flow to the high-temperature fuel gas of one-level combustion barrel 15 tail ends, a part refluxes to oil suction lining net 6 because of the backflow effect of one-level combustion barrel reducing 1, the high-temperature fuel gas that refluxes can be kept reliable firing temperature, and after glow plug 18 outages, gaseous mixture has the stable afterflame temperature that can keep spontaneous combustion; Simultaneously, this partial reflux high-temperature fuel gas helps the gasification of oil suction lining fuel oil that net 6 is inhaled, and also because of having improved the temperature of reaction zone, can strengthen combustion intensity.A small amount of combustion gas flows into secondary firing tube 17 to eliminate the dead band by the by-pass prot on the one-level combustion barrel 16, and most of combustion gas then flows into secondary firing tube 17 through reducing 1.Can be in the secondary firing tube basic after-flame of the gaseous mixture of completing combustion in the one-level combustion barrel not in the combustion gas.High-temp waste gas enters atmosphere after the heat exchanger heat absorption of heater via under the water conservancy diversion of secondary firing tube 17.
