A system and method for generating combustion aerosols from liquid fuel. The system includes a furnace with an inner heating tube having a heating tape wrapped thereabout. Further, the system includes a fuel line extending through an inlet end of the heating tube and into the heating tube, and a means for dripping the liquid fuel onto a plurality of different locations on an inner surface of the heating tube. The system further includes a power supply to power the heating tape to heat the inner heating tube to a temperature which can ignite the liquid fuel dripped onto the inner surface of the inner heating tube whereby there is an immediate combustion to form combustion products. Finally, the system includes an air line connected to the heating tube for directing compressed air through the inner heating tube to mix with the combustion products and transport the formed combustion aerosols out of an outlet end of the inner heating tube.

The disclosure relates to a burner having a container for storing liquid fuel, a fuel inlet for filling liquid fuel into the container, and a fire outlet for fire from burning liquid fuel to leave the burner. The fire outlet may function as fuel inlet or a separate fuel inlet is provided. The burner includes a stopping mechanism and an actuator for controlling the stopping mechanism. The stopping mechanism is displaced by the actuator towards a first position, when the temperature of the actuator is changed from a relatively high temperature to a relatively low temperature. The stopping mechanism is displaced by the actuator towards the second position, when the temperature of the actuator is changed from a relatively low temperature to a relatively high temperature. The disclosure also relates to a method of operating such a burner and a funnel for a burner.

A solid fuel burning system and method with a wick having a bridge is provided. The system has a melted wax reservoir, a melting grate, and the wick. The melting grate is configured to receive a solid wax. The melting grate located above at least a portion of the melted wax reservoir so that wax melted on the melting grate can be received into the melted wax reservoir. The wick has a perimeter wall, a hollow core, the bridge, and an upper exit opening in communication with the hollow core. The bridge extends across the hollow core between a first portion and a second portion of the perimeter wall. A solid fuel burning system and method with an electronic ignition system is also provided having a power source, a filament, and a filament support. The filament support positions the filament adjacent the wick or bridge within the hollow core.

The invention relates to an evaporator burner (1; 101) for a mobile heating device, comprising: a combustion chamber (3), a fuel feed line (4) for feeding liquid fuel, and an evaporator for evaporating fed fuel. The evaporator has a support body (6; 106) made of a nonporous material, comprising a fuel preparation surface (6a; 106a) which faces the combustion chamber (3) and which comes into contact with the liquid fuel. A surface structuring (11) with a plurality of depressions (11a) and elevations (11b) is introduced into the fuel preparation surface (6a; 106a) and/or into a support body (6; 106) rear face (6b; 106b) facing away from the fuel preparation surface.

An example of the combustion engine includes a central chimney having a bottom end located adjacent a combustible fuel mixture of water and alcohol. A turbine has a top side with top side hole positioned around the chimney. A generally conical turbine insulator is positioned above the turbine and around the chimney. A generally conical deflector positioned above the insulator and around a top end of the chimney. The generally conical deflector is inverted relative to the generally conical turbine insulator.
