2nd, the scattered rifle of tail gas is circumferentially distributed in around fuel feed tube, and tail gas disperses the end of rifle to tilt rifle nozzle,
The leading portion diameter for tilting rifle nozzle is more than back segment diameter, and the structure setting that this outlet for tilting rifle nozzle is tightened up adds carbon black tail gas
Jet velocity, and then, the carbon black tail gas that fuel oil and the tail gas that burning oil gun sprays into disperse the inclination rifle nozzle ejection of rifle is being cut
It is sufficiently mixed in the presence of power, improves fuel availability.
3rd, the angle of tilt axis of the horizontal axis of horizontal straight tube section with tilting rifle nozzle is 13 °, and 13 ° of angle is critical
Angle, by many experiments, angle is more than or less than 13 ° and all causes the mixed effect of carbon black tail gas, air and fuel oil to reduce,
Therefore 13 ° are an optimal angles.
4th, tilt and be evenly equipped with some ventholes in the side wall of rifle nozzle, why the setting of venthole has further added carbon black tail gas
It is being mixed into the uniformity of air cavity.
