Description
One, technical field: the present invention relates to the oil gun that a kind of oil burner uses, particularly relate to a kind of high efficiency energy-saving type oil gun.
Two, background technology: current domestic fuel oil arcola, mainly to introduce from Korea S and Italy, its burner of the homemade arcola of part also is with the production of above-mentioned two countries.The core of oil burning boiler is its burner, its technical performance directly affects the combustion position of fuel oil in boiler, the critical component of burner is an oil gun, no matter adopts which type of atomizing type, reach the internal structure that the good atomizing effect of fuel oil all depends on oil gun.
Now, the oil gun structure in the oil burning package boiler burner is to be that fuel adopts the mechanical atomization mode to design according to the lower light diesel fuel of ratio of viscosities.So the boiler of this burner can only be fuel with the light diesel fuel.Only according in the preliminary investigation of Daliang City, about more than 2,000 of this miniature boiler, a year fuel consumption reaches about 150,000 tons, mainly is distributed in bath center, hotel, sub-district heating and units such as cold weather concrete mixing plant, road asphalt heating station.
In recent years, because the price of light diesel fuel is upwards soaring at double, and the fuel cost of these enterprises is constantly increased, and has reached the stage that is difficult to bear, some units and enterprise are for the numerous and confused relatively poor but low-cost fuel oil of oil that adopts that reduces cost, this fuel oil is that heavy oil, residual oil, tar add solvent or diluent and is in harmonious proportion and forms, the bigger atomizing weak effect of its viscosity, and flame is rubescent during burning in boiler, fuel consumption is big, the chimney over-emitting black exhaust, contaminated environment, the list that has is used light diesel fuel again instead.
Chinese patent (Granted publication number be CN2144768Y, the patent No. is 92212165.6) discloses a kind of " used for industrial furnace heavy oil steam medium atomized oil gun ", and it is made of body and core body.Oily passage is arranged in the core body, and oily passage one end leads to oil inlet pipe, another termination nozzle opening, the gas passage is arranged between pellet and body, and gas passage one end leads to air inlet pipe, another termination fumarole, spout is arranged on the head, is the medium mixing chamber between spout and the nozzle opening, and fumarole and medium mixing chamber are for tangentially communicating.Steam tangentially sprays into the medium mixing chamber by fumarole, evenly mixes with fuel oil with the rotation accelerated mode, and to fuel-firing preheating, sprays then, atomizes, burns.Can improve mixing, atomizing, combustion efficiency, but black furnace igniting; energy-conservation, simple in structure, still; because a little less than the impulsive force of air-flow to fuel oil; it is not very desirable causing atomizing effect, and the time that vapour, oil mix is very short, the part elaioleucite also fully atomizing just ejection enter burning; influence completing combustion; have black smoke in the tail gas, contaminated air does not reach environmental requirement.
Three, summary of the invention:
