Abstract (en)

A liquid fuel portable heater comprises: a combustion chamber having a fuel inlet with a nebuliser (13); an electric pump (10) having an inlet (11) for suctioning said liquid fuel from a tank (6), and an outlet (12) connected to said nebuliser (13); a control unit (20) configured so that, when the heater is turned on, said control unit (20) supplies the electric pump (10) with a sequence of pulses with a non-zero voltage, and pause intervals with a substantially zero voltage alternating with said pulses, wherein the average duration of the pulses is less than the average duration of the pause intervals. The heater may furthermore comprise a thermoelectric power generator. In addition, a method for controlling an electric power supply of a fuel electric pump (10) of a liquid fuel portable heater by means of an electric control unit (20) configured to control said electric power supply, comprising a step of electrically supplying said electric pump (10), once the heater is turned on, with a sequence of pulses with a non-zero voltage, and pause intervals with a substantially zero voltage alternating with said pulses, wherein the average duration of the pulses is less than the average duration of the pause intervals.
