A burner assembly having improved flame length and shape control is presented, which includes in exemplary emodiments at least one fuel fluid inlet and at least one oxidant fluid inlet, means for transporting the fuel fluid from the fuel inlet to a plurality of fuel outlets, the fuel fluid leaving the fuel outlets in fuel streams that are injected into a combustion chamber, means for transporting the oxidant fluid from the oxidant inlets to at least one oxidant outlet, the oxidant fluid leaving the oxidant outlets in oxidant fluid streams that are injected into the combustion chamber, with the fuel and oxidant outlets being physically separated, and geometrically arranged in order to impart to the fuel fluid streams and the oxidant fluid streams angles and velocities that allow combustion of the fuel fluid with the oxidant in a stable, wide, and luminous flame. Alternatively, injectors may be used alone or with the refractory block to inject oxidant and fuel gases. The burner assembly affords improved control over flame size and shape and may be adjusted for use with a particular furnace as required.
A method of controlling flame length using a liquid fuel atomizer comprising a first hollow cylinder, the first hollow cylinder having a fuel exit end with a single fuel exit fluidly communicating with a plurality of hollow elementary conduits, and an outer nozzle formed from a second hollow cylinder extended by a profiled part comprised of two symmetrical cowls and having a fuel exit end and having a plurality of fuel exits, the outer nozzle having an internal diameter greater than an external diameter of the first hollow cylinder, the second hollow cylinder completely surrounding the single fuel exit of the first hollow cylinder, the profiled part having an interior which is pierced by a plurality of channels, the plurality of channels being equivalent in number to the plurality of hollow elementary conduits, the channels merging with an interior of the second hollow cylinder and terminating at the fuel exit end of the second hollow cylinder, to form a space for flow of atomizing fluid surrounding the hollow elementary conduits, the first hollow cylinder having an axis, the method comprising increasing or decreasing a delivery rate of the atomizing fluid.
A burner assembly having improved flame length and shape control, the burner assembly comprising a refractory block adapted to be in fluid connection with sources of oxidant and fuel, the refractory block having a fuel and oxidant entrance end and a fuel and oxidant exit end, the exit end having fuel exits and oxidants exits, the refractory block further having a plurality of fuel cavities, at least two of the fuel cavities defining a first fuel plane, and a plurality of oxidant cavities defining a second oxidant plane, the fuel cavities being more numerous than the oxidant cavities, at least one of the fuel cavities having positioned therein a liquid fuel atomizer comprising a first hollow cylinder, the first hollow cylinder having a fuel exit end with a single fuel exit fluidly communicating with a plurality of hollow elementary conduits, and an outer nozzle formed from a second hollow cylinder extended by a profiled part comprised of two symmetrical cowls and having a fuel exit end and having a plurality of fuel exits, the outer nozzle having an internal diameter greater than an external diameter of the first hollow cylinder, the second hollow cylinder completely surrounding the single fuel exit of the first hollow cylinder, the profiled part having an interior which is pierced by a plurality of channels, the plurality of channels being equivalent in number to the plurality of hollow elementary conduits, the channels merging with an interior of the second hollow cylinder and terminating at the fuel exit end of the second hollow cylinder, to form a space for flow of atomizing fluid surrounding the hollow elementary conduits, the first hollow cylinder having an axis.
