Pressure atomizing type burner for an engine independent heating system

A heater (independent vehicle heater) which can be operated in a particularly wide range between full load and partial load, e.g., 1:10 to 1:15, is shown. This is achieved by the annular space surrounding the combustion chamber being divided into two partial compartments and by supplying the combustion air to these partial compartments. A control element (back-pressure-controlled control element), which separates some of the air passage openings between the annular space and the combustion chamber from the passage of air, is arranged in the combustion air line.

Liquid fuel-operated heater for vehicles

An arrangement for the retention of an ultrasonic atomizer has the advantage of little influence on the vibration system due to the fuel supply connections and reduced bearing surface of the ultrasonic atomizer. The construction permits quick installation through since the retention is effected with a clamp. The fuel supply occurs via a bore opening into an annular channel in the structural part in which the ultrasonic atomizer is mounted. The atomizer is retained by a small bearing surface. A radial bore in a lug of the ultrasonic atomizer is a component part of the horn of the atomizer.

Liquid fuel ultrasonic atomizer construction for a heater

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.

Ultrasonic atomizing burner

A burner for air heaters comprises a first wall structure defining an ignition chamber with an ultrasonic atomizer discharging into the ignition chamber and with means for delivering primary air into the ignition chamber for ignition by suitable ignition device to form an igniting gas mixture. The construction includes a second wall arrangement which is adjacent the ignition chamber and which defines a primary combustion chamber which has a passage for the ignited gas mixture from the ignition chamber and also for secondary air so as to complete the combustion in the main combustion chamber. The main combustion chamber in turn is connected downstream and into an exhaust diffuser in which the completely burnt gases are delivered to a place of use for heating an area such as a space in a motor vehicle. In one construction, the combustion chamber is defined within a perforated tube which has a perforated bottom or rear wall facing an ignition chamber which is defined with an outer tube which is also perforated to provide for the inflow of the primary air. The ignition device is mounted in the outer tube adjacent the atomizer so as to ignite the fuel with the primary air and direct this ignited mixture into perforations of the main combustion chamber for continued burning therein. In another embodiment the primary chamber is defined by a perforated wall which defines an area within the outer perforated housing which comprises the ignition chamber having the atomizer in an igniting element. This ignition chamber communicates through perforations in the surrounding wall with an inlet for the primary air and one or more inlets for the secondary air in the remaining space within the outer housing which defines the main combustion chamber.
