Abstract

A furnace is disclosed adapted to provide for the complete smokeless combustion of liquid or partially liquid materials. Said furnace can be advantageously used when said materials contain toxic components or compounds. The subject furnace includes a hollow cylindrical body provided at the lower end thereof with a substantially cylindrical body whose opposite end faces carry radially extended projections, of a substantially circular shape. Together with the side surface of said substantially cylindrical body, and with the inner surface of said hollow cylindrical body, said projections enclose an essentially annular combustion chamber. Inside the cylindrical body there is provided passages for supplying to the combustion chamber the materials to be burnt, as well as fuel gas and combustion sustaining gas, said supply process being performed in a substantially radial direction from the center of said cylindrical body out towards said combustion chamber, wherein the combustion takes place both because of the flame effect and because of the cylindrical body and the expansions thereof growing red hot.
