Patent ID: 6988885

Claim:
An evaporative burner, comprising: a combustion chamber, an evaporative medium ( 34 ) for feeding fuel vapor into the combustion chamber ( 52 ), a first heating device ( 70 ) with a heating region, including at least one ignition heating element ( 70 ) for ignition of fuel vapor present in the combustion chamber ( 52 ), the first heating device projecting with at least its heating region into the combustion chamber ( 52 ), a second healing device ( 72 ), including at least one evaporating heating element ( 72 ) associated with the evaporative medium ( 34 ) for affecting its evaporation characteristic, said at least one evaporating heating element ( 72 ) comprising an electrically operated heating element having an electrical resistance that rises with increasing temperature, and a control device by which heating power of at least the second heating device ( 72 ) is adjusted, and a monitoring module that monitors the heating power or the required heating power of the second heating device ( 72 ) and senses the presence of evaporation of fuel, depending on the result of monitoring.
