Abstract

PURPOSE: To vary combustion rates in a wide range at approximate uniform air/ fuel ratio without impairment of quality of the discharged gases by a method wherein a vertically slidable intermediate cylinder is provided outside a wick guiding cylinder to adjust areas of air openings by sliding the intermediate cylinder up and down.

CONSTITUTION: Blue cylindrical flame spreads upward from the top edge of the intermediate cylinder 4 to inside top of an outer cylinder 14 upon igniting a wick which is raised up to a preset position by turning a knob 18. Inside air is supplied through air ports 3a on an inner cylinder and ambient air taken from air intakes 15 is supplied through air openings on the intermediate cylinder 12 and air openings on the wick guiding cylinder 13, but partly through air ports on the intermediate cylinder 4a into the combustion chamber. In addition to the above, the rest of air quantity is supplied into the combustion chamber through the space between the intermediate 4 and the outer cylinders 14. Proper air/fuel ratio can be maintained in a way that as the flames becomes bigger with the intermediate cylinder 4 being lowered, the air opening areas become larger, but as the falme becomes samller with the intermediate cylinder 4 being raised, the air opening areas become smaller.
