  • Combustion apparatus with atomizer and method of controlling same
    Patent number: 5127822
    Abstract: Provided is an atomizer-equipped combustion apparatus including an atomizing device for atomizing a fuel, a spray chamber for mixing the fuel atomized by the atomizing device with air to form a mixture, and for moving the mixture downwardly toward an opening at a distal end portion of the spray chamber, and a wind box provided so as to surround a lower portion of the spray chamber for forming a combustion space between itself and the spray chamber, the wind box being provided with a plurality of air supply holes facing a lower portion of the spray chamber. A mixture of external air and a fine spray of fuel produced by the atomizer can be ignited instantaneously by means of a comparatively simple structure, odors produced at igition and extinguishment can be greatly suppressed and a high turn-down ratio can be obtained.

  • Ultrasonic atomizing apparatus
    Patent number: 4799622
    Abstract: An ultrasonic atomizing apparatus including an ultrasonic vibration generator and an ultrasonic vibrator horn having a cylindrical section connected at one end to the ultrasonic vibration generator and having a flared portion connected to the other end of the cylindrical section. The flared portion is flared and enlarged in diameter towards the tip end of the horn and is adapted to atomize liquid material on the flared portion as the liquid material is supplied from a liquid material supply nozzle to the flared portion. A hollow recess is formed in the flared portion opening toward the tip end of the horn. The geometry of the hollow recess is such that the cross-sectional area of the flared portion of the horn in any plane perpendicular to the longitudinal axis of the horn is the same as the cross-sectional area of the flared portion in all other planes perpendicular to the longitudinal axis of the horn.

  • Ultrasonic atomizing vibratory element having a multi-stepped edged portion
    Patent number: 4726524
    Abstract: The present invention consists of an ultrasonic atomizing vibratory element having a multi-stepped edged portion formed around the outer periphery thereof. The edged portion has at least two steps each defining an edge and being adapted to be supplied with liquid to be atomized. The vibratory element is provided with a liquid supply groove extending generally longitudinally to supply the liquid to the edge portion in a consistent and stable manner.
