Abstract
A high turn down ratio flare tip assembly, that allows for both low and high flowrate and pressure flows using a single flare. The flare assembly comprising a nozzle tube connected to the waste stream fuel inlet at one end. The other end of the flare tip assembly providing a seat for a conical structure with flow through orifices/ports that allow the waste stream to flow therethrough during low pressure operation. The conical structure connected to one end of a connecting rod, the connecting rod extending longitudinally downward through the nozzle tube and connected to a spring assembly. The flare tip assembly is designed to allow low flow and pressure to pass through the cone orifices, and during high flow and pressure operation, the cone is unseated from the nozzle tube, allowing the waste stream to flow therethrough. The flare tip assembly also includes a slotted/holed shroud that allows for smokeless combustion of the waste stream during high flow and pressure conditions.
