Definitions

• U. S. Patent 4,011,995 titled Burner Nozzle Assembly discloses a nozzle assembly which internally mixed compressed gas with flammable fluids.
• the nozzle assembly uses the same compressed gas to shape and control the compound mixture of gas and flammable fluid after it exits the nozzle assembly.
• Receiver 50 also has a plurality of openings 74 which extend radially through its exterior between o-rings 52 and 53.
• Throat means 51 also has a plurality of internal injection orifices 75 adjacent to openings 74 in receiver 50. Internal injection orifices 75 and openings 74 cooperate to provide openings between chamber means 68 and longitudinal passageway 40 which allow mixing of atomizing fluid and primary fluid prior to exiting from throat means 51.
• the primary fluid being disposed of is pumped through supply line 31 and connection 31a into cylindrical housing 48.
• Primary fluid flows from housing 48 through openings 54 into longitudinal passageway 40.
• a secondary fluid such as diesel fuel can be injected into longitudinal passageway 40 via supply line 26 and flow tube means 38.
• the secondary fluid mixes with the primary fluid within throat means 51 to improve the combustion of the primary fluid.
• Atomizing fluid is also injected into longitud ⁇ inal passageway 40 via supply line 28, connection 28a, cylindrical housing 49, chamber means 68, openings 74 and internal injection orifices 75.
• the atomizing fluid due to its injection angle causes violent swirling and mixing of the primary and secondary fluids.
• Air is preferably used as the atomizing fluid.
• the resulting compound mixture of air, primary fluid and secondary fluid exits throat means 51 at greatly increased velocity due to the expansion of the air. Also, violent mixing of air with the primary fluid reduces its effective viscosity and improves its combusion characteristics.
• Atomizing fluid is also focused on the compound mixture exiting throat means 51 by ports 73. This use of atomizing fluid external to throat means 51 controls the shape of the compound mixture and the resulting flame after the compound mixture is ignited. Atomizing fluid from ports 73 also supplies additional oxygen to facilitate more complete combustion (less smoke) of the primary fluid. An electrical ignitor (not shown) and gas supplied through supply line 30 are used to ignite the compound mixture exiting from throat means 51.
• Plug means 70 can be inserted into receiver 50.
• a blank end cap (not shown) can be attached to threads 47 and nozzle assembly 35 operated with only primary fluid and atomizing fluid flowing therethrough.
• Atomizing fluid is directed from connection 28a into longitudinal passageway 40 via chamber means 68.
• Figure 6 demonstrates the compound angle of internal injection orifices 75 with respect to the longitudinal axis of throat means 51.
• Figure 5 illustrates how rotation of throat means 51 relative to receiver 50 ' can vary the radial alignment of openings 74 relative to internal injection orifices 75. The alignment shown in Figure 5 results in the maximum flow of atomizing fluid into longidutinal passageway 40.
• the major variation between nozzle assembly 35 and nozzle assembly 80 is the installation of secondary fluid container 84 on the exterior of end cap 66.
• Container 84 is generally cylindrical in shape with opening 85 therein to receive end cap 66.
• Container 84 has the general shape of a toroid.
