At present, the method for the emulsion fuel that several burnings mix by petroleum fuel, water and low quantity of surfactant has been proposed, so that reduce the oil-fired consumption figure as kerosene, light oil and reduce NO
x, cigarette ash slag and similar emission.It has been generally acknowledged that the weight mixing ratio of water in flammable emulsion fuel has a practical limit, promptly about 1-10% (weight), thereby increase fuel consumption because water will absorb latent heat.
Japanese patent application (JP-A) publication number No.7-313859 discloses a kind of production method that the oil droplet diameter is the emulsion fuel of 0.5 μ m that contains, and this method stirs oil and water and realizes in a simple tank diameter.But there is a problem in this method, promptly repeats stirring and can make the emulsion fuel breakdown of emulsion that obtains, because its use separate unit tank diameter and mixing speed are very fast relatively.Though stirring at low speed not too can make the emulsion fuel breakdown of emulsion thereby can solve the breakdown of emulsion problem, make emulsion fuel like this and will spend the long period.
In addition, Japanese patent application (JP-A) publication number No.55-23812 discloses a kind of liquid-fuel burner that has hotair chamber, and air is heated to 200-400 ℃ and mixes with the emulsion fuel of evaporation and mixing material is burnt in this heating clamber.
But above-mentioned located by prior art needs hotair chamber and evaporation component, so the structure of burner is complicated.
Although Japanese patent application (JP-A) publication number No.7-313859 has illustrated above-mentioned emulsion fuel production method, burner is not added reveal.
And, press prior art, the emulsion fuel of producing will temporarily leave the overcompression of container back warp in and be transported to burner again.But when the fuel of storing when compressing as mentioned above because violent variation takes place pressure, the emulsion fuel of being stored is by breakdown of emulsion.The emulsion fuel efficiency of combustion of breakdown of emulsion is low, and produces carbon deposit and black smoke in burner.
Because stir, the emulsion fuel of generation has bigger kinetic energy.But kinetic energy has just disappeared when emulsion fuel is stored in the container under static conditions.After this, the compressed burner that is transported to of the emulsion fuel of storage, kinetic energy can not be utilized, and therefore, capacity usage ratio is poor.

Simultaneously, emulsion fuel burner 40 is identical with first, second above-mentioned embodiment, so explanation is omitted.
The operation of this embodiment is discussed below.The ratio of carrying above at first using produces emulsion fuel.
Also by control circuit control, the kerosene temperature that records according to thermometer 118 makes the kerosene temperature reach predetermined value to heater 110.
Control circuit makes above-mentioned revolution, rotates thereby drive tumbler 214,144 rotates thereby revolving part 138 and rotating shaft 144 are all followed around the shaft.
Air, water, kerosene and surfactant are carried by air supply pipe 115, feed pipe 112, kerosene supply pipe 108 and surfactant supply pipe 114 with above-mentioned predetermined ratio, they mix mutually, rely on the pressure supplied in water tank 104, coal oilcan 102, surfactant case 106 and the gas cylinder simultaneously and, rise by passage 154 gradually with the unlifting pressure of rotating shaft 144 rotating blades 180.Because blade 180 rotates with rotating shaft 144, so can be with the steady and effectively feed channel 154 and increase lifting force of air, water, kerosene and surfactant along passage 154.
When the mixed liquor of air, water, kerosene, surfactant progressively mixes mutually along passage 154 risings, because the viscosity of kerosene, and with the rotation of expansion segment 140 outer surfaces of tumbler 138, mixed liquor rotates along garden Zhou Fangxiang with the rotating speed that is lower than tumbler 138.Mixed liquor is subjected to the effect of radial centrifugal force when garden Zhou Fangxiang rotates.This centrifugal force can resolve into two vectors along passage 154 directions and vertical direction thereof.Owing to have component to affact on the mixed liquor along passage 154 directions, even there is the component on passage 154 vertical direction to cause frictional force, mixed liquor also can be to rising when further quickening mixing.Because expansion segment 140 enlarges along with highly increasing, therefore garden Zhou Changdu also increases on the horizontal cross-section when continuing to rise, and speed also increases as a result.
Owing to also be free pneumatic transmission to go into by the above, and air also can produce bubble in water, so worry may form air layer in passage 154.But because of on the expansion segment 140 and fixture 136 therewith on expansion segment 140 interior surface opposing (the present embodiment is an expansion segment 140) baffle plate 141 is arranged, fall so air layer is destroyed.
