Abstract
Abstract A burner nozzle for burning petroleum products. The burner nozzle includes a fluid conduit with an air jacket disposed therearound such that a dead air space is defined therebetween to prevent fluid leakage from entering the air jacket. The burner nozzle comprises a replaceable air jetting assembly which provides an annular stream of air, either cylindrical or conical in configuration, which impinges the fluid stream exiting the nozzle for atomization thereof. The jetting assembly includes a replaceable and interchangeable jetting insert. A swirl chamber is provided in the fluid conduit to impart a swirling motion to fluid flowing therethrough. The swirl chamber is clamped in position on opposite sides thereof so that it is always in compression, thus allowing use of non-weldable materials. One embodiment has a variable air jetting orifice.
