Ultrasonic atomizing burner

摘要

An ultrasonic atomizing burner for smaller heating apparatus particularly for mobile spaces, such as motor vehicles comprises an atomizer which has a fuel inlet and which is equipped with an atomizer discharge plate and a structure skirting the plate which defines a combustion air flow space for 1% at most of the combustion air amount. This structure includes a cylindrical combustion chamber having a forward discharge end with a flame baffle and with a heating gas outlet tube connected to the discharge end for the axial flow of the combustion gases. The combustion chamber has an ignition zone which is provided with wall bores for admitting primary air and it includes a spark plug in the ignition zone for igniting the combustion gases and the primary combustion air. The combustion chamber also has a burnout zone which is provided with wall slots for admitting secondary air downstream of the primary air.
