Claims9
A burner comprising:
- a burner element formed of a slab of material which is adapted and arranged to hold liquid fuel by capillary action and defining air passageways therethrough for the passage of combustion air to a combustion zone at the surface of the burner element;
- means supplying fuel under pressure in said element in an amount in excess of that required to saturate said element thereby to cause the element to be flushed and to remove carbon build up therefrom during the entire normal operation of the burner, said excess fuel dripping from the underside of the element said means including an elongated pipe having a plurality of orifices abutting the burner slab material and directed toward the combustion zone for directing the fuel into the burner slab material;
- and means for collecting and recycling the excess fuel to said supplying means;
- the combustion air and fuel vapors from the burner element being mixed and reacted above said element.
