Moreover, theburner 100 can be disposed within a chimney or vented enclosure. - Referring now to
FIG. 2 , a diagram of asmokeless flare burner 100 in accordance with one embodiment of the present invention is shown. Thesmokeless flare burner 100 includes ahousing 210, an orificedgas nozzle 212, aconical diffuser 214, two ormore support members 216, and aretention cap 218. Thehousing 210 has alongitudinal axis 220, a firstcylindrical portion 222, a firsttapered portion 224 connected to the firstcylindrical portion 222, a secondcylindrical portion 226 connected to the firsttapered portion 224, a secondtapered portion 228 connected to the secondcylindrical portion 226. The firsttapered portion 224, the secondcylindrical portion 226 and the secondtapered portion 228 form a venturi. The orificedgas nozzle 212 is aligned with thelongitudinal axis 220 and disposed within thehousing 210 proximate to the firstcylindrical portion 222 and the firsttapered portion 224 of thehousing 210. Theconical diffuser 214 is aligned with thelongitudinal axis 220 and has avertex 230 disposed within the secondtapered portion 228 of thehousing 210 and abase 232 substantially perpendicular to thelongitudinal axis 220. The two ormore support members 216 are attached to the secondtapered portion 228 of thehousing 210 and theconical diffuser 214 to create agap 234 between the secondtapered portion 228 of thehousing 210 and theconical diffuser 214.

FIG. 3 , a diagram of asmokeless flare burner 100 mounted on a fixedstack 302 in accordance with one embodiment of the present invention is shown. The fixedstack 302 includes several sets of four guy eyelets 304. A pilot origniter 306 is disposed proximate to the gap of theflare burner 100 and is attached to a channel (e.g., 2″) 308. In this example, the total height of the fixedstack 302 andburner 100 is 44′-3″ with agas inlet 310 located 4′ above ground level. - Referring now to
FIG. 4 , a diagram of a dual pressure flare burning 400 in accordance with another embodiment of the present invention is shown. The dualpressure flare burner 400 has a similar configuration as shown inFIG. 1 , but includes a lowpressure gas nozzle 402,expansion chamber 404 andexit 406. The low pressure gas and high pressure gas are not manifolded together. Instead, the low pressure gas is fed into theexpansion chamber 404 having asmall exit 406 proximate to the high pressure gas exit (gap 234). Theflare burner 400 has numerous operating advantages. For example, complete combustion will occur when high pressure gas or low pressure gas are provided to theburner 400 at different times, as well as when high pressure gas and low pressure gas streams are provided to theburner 400 at the same time. The size of theburner 400 is scalable. - The
smokeless flare burner 400 includes ahousing 210, an orificed highpressure gas nozzle 212, aconical diffuser 214, two ormore support members 216, aretention cap 218, a lowpressure gas nozzle 402, anexpansion chamber 404 and anexit 406. Thehousing 210 has alongitudinal axis 220, a firstcylindrical portion 222, a firsttapered portion 224 connected to the firstcylindrical portion 222, a secondcylindrical portion 226 connected to the firsttapered portion 224, a secondtapered portion 228 connected to the secondcylindrical portion 226. The firsttapered portion 224, the secondcylindrical portion 226 and the secondtapered portion 228 form a venturi. Theorificed gas nozzle 212 is aligned with thelongitudinal axis 220 and disposed within thehousing 210 proximate to the firstcylindrical portion 222 and the firsttapered portion 224 of thehousing 210. Theconical diffuser 214 is aligned with thelongitudinal axis 220 and has avertex 230 disposed within the secondtapered portion 228 of thehousing 210 and a base 232 substantially perpendicular to thelongitudinal axis 220. The two ormore support members 216 are attached to the secondtapered portion 228 of thehousing 210 and theconical diffuser 214 to create agap 234 between the secondtapered portion 228 of thehousing 210 and theconical diffuser 214. Theretention cap 218 is attached to thebase 232 of theconical diffuser 214 and extends beyond aperimeter 236 of thebase 232 of theconical diffuser 214. Theexpansion chamber 404 is disposed around the exterior secondcylindrical portion 226. The lowpressure gas nozzle 402 is connected to theexpansion chamber 404 usingtubing 408. Thetubing 408 may include a flaredportion 410 proximate to the lowpressure gas nozzle 402 and anopening 412 that creates a venturi effect to mix the low pressure gas withoutside air 414. Theexit 406 is proximate to thegap 234 between the secondtapered portion 228 of thehousing 210 and theconical diffuser 214, such the a compete combustion of both the low pressure gas and the high pressure gas is provided. Thelow pressure nozzle 402 is fed from alow pressure supply 416 proximate to or attached to thestack 102. Thehousing 210 and other components will typically be made of a heat resistant material, such as 310 stainless steel or other suitable material. - A gas exiting the
orificed gas nozzle 212 provides a motive force that induces a flow ofair 238 into the firstcylindrical portion 222 of thehousing 210. The flow ofair 238 into the firstcylindrical portion 222 of thehousing 210 mixes with the gas within thehousing 212 and an air outside thegap 234 completes a combustion of the gas. To provide proper operation, a flow rate of a gas exiting theorificed gas nozzle 212 should be no less than approximately 30% of a maximum flow rate of the gas. Theretention cap 218 deflects the air-gas mixture to ensure a substantially complete burn of the gas. - The
burner 400 may include two or moreair intake openings 240 within the firstcylindrical portion 222 of thehousing 212. Theair intake openings 240 can be slots, holes or types of openings as long as they provide a sufficient flow ofair 238. Similarly, thegap 234 and/or the two ormore support members 216 can be a tapered cylinder having two or more openings (e.g., slots, holes, etc.). Alower cap 242 may also be attached to the firstcylindrical portion 222 substantially perpendicular to thelongitudinal axis 220. - The
retention cap 218 may have a diameter greater than or equal to a maximum diameter of the secondtapered portion 228 of thehousing 212. Moreover, the shape of theconical diffuser 214 can be substantially parallel to a shape of the secondtapered portion 228 of thehousing 210. In one embodiment, theburner 400 has a height to diameter ratio of between 2.0 and 2.2 to 1. In another embodiment, theburner 400 has a height to diameter ratio of approximately 2.1 to 1. Theburner 400 may also have an effective cross-sectional area of thegap 234 of approximately 250 times a cross-sectional area of theorificed gas nozzle 212. In addition, the effective cross-sectional area of thegap 234 may be greater than a cross-sectional area of the secondcylindrical portion 226 of thehousing 212. A cross-sectional area of the secondcylindrical portion 226 of thehousing 210 can be approximately 35 to 40% of a cross-sectional area of the firstcylindrical portion 222 of thehousing 210. - It will be understood by those of skill in the art that information and signals may be represented using any of a variety of different technologies and techniques (e.g., data, instructions, commands, information, signals, bits, symbols, and chips may be represented by voltages, currents, electromagnetic waves, magnetic fields or particles, optical fields or particles, or any combination thereof).
