Abstract
A device which includes a porous burner head capable of containing a liquid fuel in a liquid state and in which air is supplied to the surface of the burner head to vaporize and burn the fuel contained therein. The burner head is made of a heat-resistant porous material having extending therethrough minute channels which are predominantly up to 100 .mu.m in diameter and give the burner head a porosity of at least 25%. The burner head is capable of raising the liquid fuel at a rate of at least 0.001 g/cm.sup.2.min to a height of up to 70 mm. The use of the burner head assures clean combustion and high combustion efficiency.
