Abstract
Abstract A portable adjustable flow rate flare for smokeless burning of viscous liquid fuels such as crude oil, which comprises an assembly of four coaxial circular manifolds one each for pressurized fuel, water, atomizing medium, and gas, supplying a plurality of burner heads, radially spaced, symmetrically, about at least the upper portion of the circular manifolds. The planes through each of the manifolds are parallel to each other and coaxial and adapted for mounting with axis horizontal on a base structure, so that it can be moved from one location to another. Each of the burner heads comprises a central tube receiving pressurized fuel leading to an orifice of selected size and continuing downstream from the orifice with a tubular portion of selected diameter. An annular chamber about the burner tube provides pressurized atomizing medium to the inside of the burner tube through a plurality of spaced openings so as to mix at high velocity with the flow of oil from the orifice and to atomize the oil. Ignition means are provided to ignite the flame at the tip of the burner head. Water spray may be provided at each burner head.
