Abstract
A safety device for preventing uncontrolled burning in wick-fed liquid fuel burners employs a thermal barrier between the heat of the combustion process and a removable fuel tank 60. Also, a fuel containment compartment (24) and fuel containment sump (44) are provided to receive fuel from the fuel chamber (40) when excess fuel is delivered to the fuel chamber from the removable fuel tank. When the fuel in the fuel chamber exceeds a predetermined level, a warning gauge needle 90 is deflected, alerting the user of the liquid fuel burner to a dangerous condition.
Claims20
An apparatus for preventing flareup in a liquid fuel burner of the type comprising:
- (a) a removable liquid fuel tank,
- (b) a fuel chamber,
- (c) an automatic wick extinguishing unit,
- (d) a combustion chamber having a wick,
- (e) a reflector adjacent said combustion chamber,
- (f) a cabinet having a lid over said removable tank, and
- (g) a tank guide which holds said tank in a vertical position in said cabinet,
- said fuel chamber being arranged to carry liquid fuel from said removable tank to said wick of said combustion chamber,
- said apparatus comprising a thermal barrier for isolating said removable tank from the heat of said reflector and said combustion chamber.
An apparatus for preventing flareup in a liquid fuel burner of the type comprising:
- (a) a removable liquid fuel tank,
- (b) a fuel chamber,
- (c) an automatic wick extinguishing unit,
- (d) a combustion chamber having a wick,
- (e) a reflector adjacent said combustion chamber, and
- (f) a cabinet having a lid over said removable tank,
- said fuel chamber being arranged to carry liquid fuel from said removable tank to said wick of said combustion chamber,
- said apparatus comprising excess fuel containment means for receiving and holding any excess fuel which flows into said fuel chamber from said removable tank,
- said excess fuel containment means comprising a fuel containment compartment connected to and positioned above said fuel chamber.
A method of preventing flare-up in a liquid fuel burner of the type comprising a liquid fuel removable tank, a fuel chamber, an automatic wick extinguishing unit, and a combustion chamber having a wick, a reflector, and a cabinet having a lid over said removable tank, where said fuel chamber carries liquid fuel from said removable tank to said wick of said combustion chamber, comprising the steps of:
- insulating said removable tank from the heat of said reflector, and
- containing elevated levels of fuel in said fuel chamber by capturing fuel which exceeds a predetermined level in said fuel chamber by providing an excess fuel containment compartment which is connected to and positioned above said fuel chamber.
