Definitions

  • This invention relates to the art of flaring low pressure hydrocarbon gases, smokelessly.
  • Wind is another problem with burning low pressure hydrocarbons above an elevated stack. If there is insufficient pressure to cause the flame to 'stand-up' the flames will 'lick' the side of the stack causing its destruction, besides the constant problem of maintaining ignition. Standing the flames upward is preferred.
  • An object of this invention is to provide an apparatus which will impart additional energy to a low pressure waste gas which is to be flared since the gas, being a relatively low pressure cannot of its own energy inspirate the necessary combustion air for complete smokeless combustion.
  • the flare apparatus of this. invention for inducing or imparting the kinetic energy to a low pressure waste gas stream which is to be burned includes a burner structure having a low pressure waste gas supply conduit which terminates at a burning tip.
  • a high pressure fluid manifold surrounds the supply conduit and includes, adjacent the tip a plurality of outwardly extending hollow arms. One or more openings in the top of each of the arms are angularly oriented such that high pressure gases being directed therefrom are directed inwardly and upwardly or along the direction of the axis of the low pressure gas conduit above the tip. Preferrably, the angle of said openings or the direction of high pressure gas flow is greater than 45 0 to the horizontal or tip surface.
  • a high pressure fluid typically a gas is supplied to the manifold. The injection of the high pressure gas causes the inspiration of air and turbulence to the low pressure gases flowing from the center conduit for complete and smokeless combustion.
  • Another object of the invention is to provide a method of burning low pressure waste gases by the induction of additional kinetic energy thereto.
  • the numeral 10 generally indicates the flare apparatus of this invention.
  • the low pressure gas conduit 12 extends to a tip 14.
  • Surrounding the conduit is a coaxial manifold 16 and a plurality of outwardly extending arms 20 that are in communication with the manifold 16.
  • In each of the arms are one or more openings 22, of size and oriented to the horizontal or tip surface 14 so as to not only impart kinetic energy to the low pressure gas flowing upwardly in conduit 12 but also maintain the burning above tip 14 in a stand-up condition substantially unaffected by wind conditions.
  • an angle A of at least 45° and openings 22 of size relative to the high pressure gas to create sonic velocity therefrom.
  • FIGURES 3 and 4 indicate another embodiment of the use of the apparatus of this invention wherein like numerals are used for like parts as shown in FIGURES 1 and 2.
  • a central emergency flare stack 30 is provided for venting large quantities of waste gas or high pressure waste gas, whichever the case may be.
  • Surrounding the tip of waste flare conduit 30 are one or more flare burner apparatus 10 extending circumferentially around the stack.
  • Supply manifold 32 for the low pressure waste gas and 34 for the high pressure fluids are provided. This embodiment provides flexibility to plants where low pressure and high pressure waste gases are to be flared.
  • FIGURE 5 represents a flow sequential system for waste gases which may vary at low flow or pressure rates to an extreme high flow or pressure rate.
  • waste gas enters via conduit 50 and 52 to one or more burners 10a via conduit 12.
  • high pressure gas will enter via conduit 60 through 62 into the manifold system 16 surrounding the low pressure conduit 12 as best shown in FIGURE 2.
  • valve 70 controlling the high pressure fluid and valve 72 to the low pressure gas which will allow for passage through respective conduits 63 and 64 and 54 and 55.
  • conduit 50 Further increase in flow or pressure of the waste gas via conduit 50 additional burner systems 10c, 10d, etc. may be utilized or an emergency flare which can handle larger quantities of gas may be provided by flow through conduit 56 and thence 58.
  • the flow being controlledc by valve 74 and/or flow control through pipe 76 into a water seal 78, the outlet 80 of which will enter conduit 58 to an emergency flare stack, not shown.
  • the high pressure fluids useful in the apparatus of this invention includes gaseous or vaporous smoke suppressants, such as steam or air, inert gases or combustible high pressure gases.
