Abstract

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.

Burner A burner for burning liquid fuel, the burner comprising a container for storing the liquid fuel, an opening allowing filling of liquid fuel through the opening and into the container, and a fire outlet for fire from burning liquid fuel to leave the burner,

the burner also comprising a stopping means for not allowing, preferably for preventing, filling of liquid fuel through the opening and into the container of the burner,
where the burner comprises an actuator for displacing the stopping means between a first position and a second position, and vice versa, and where the actuator is positioned in a part of the burner being heated by fire from burning liquid fuel,
where the actuator is provided in a position, in relation to the fire outlet, resulting in the actuator changing temperature depending on a temperature of the burner within the vicinity of the opening for filling liquid fuel into the container of the burner,
where change of the temperature of the actuator because of change of temperature of the part of the burner being heated by fire from burning liquid fuel, results in change of a geometrical shape of the actuator, and
the actuator and the stopping means being mutually connected for the actuator displacing the stopping means when a change of geometrical shape of the actuator occurs,
where change of the geometrical shape of the actuator results in displacement of the stopping means, via the connection, between the first position and the second position, towards the first position or towards the second position, and
where the stopping means is displaced towards the first position, when the temperature of the actuator is changed from a relatively high temperature to a relatively low temperature, and in which first position the stopping means is allowing liquid fuel to be filled into the container of the burner, and
where the stopping means is displaced towards the second position, when the temperature of the actuator is changed from a relatively low temperature to a relatively high temperature, and in which second position the stopping means is not allowing liquid fuel being filled into the container of the burner.
