Claims

[Claims for Utility Model Registration] (1) A combustion chamber formed to allow outside air to be introduced from a plurality of parts spaced apart from each other, and a fuel provided in the combustion chamber that is introduced as atomized by ultrasonic vibration. an ultrasonic atomizer that performs combustion by mixing with outside air; a primary ignition means for igniting a part of the mixture with outside air flowing into the vicinity of the installation position of the ultrasonic atomizer and using the combustion heat to turn the remainder of the mixture into fuel gas; Provided downstream in the direction of movement of the fuel gas generated by the primary ignition means, and formed by premixing the moving fuel gas with outside air flowing into the combustion chamber downstream in the direction of movement of the fuel gas. secondary ignition means for performing steady combustion by igniting the air-fuel mixture; and outside air introduction amount adjusting means for freely adjusting the amount of outside air introduced into the combustion chamber downstream in the direction of movement of the fuel gas. and the outside air introduction amount adjusting means is configured to control the air-fuel mixture formed by the secondary ignition means by premixing the fuel gas and the outside air flowing downstream in the direction of movement of the fuel gas. Equipped with an ultrasonic atomizer characterized in that the amount of outside air introduced is controlled so that the air-fuel ratio is always within the combustible range during ignition, steady combustion, and extinguishing. combustor. (2) The external air introduction amount adjusting means is a secondary air control damper that can freely adjust the introduction amount of secondary air flowing into the combustion chamber downstream in the direction of movement of the fuel gas according to the opening degree; The secondary air control damper is provided with an opening sensor that detects the opening and outputs an electric signal according to the detected opening, and a drive means that drives the secondary air control damper. The combustor with an ultrasonic atomizer according to claim 1, wherein a solenoid or a stepping motor is used for the combustor.
