- Glycerin, or glycerol, is a byproduct of biodiesel and soap manufacturing. Although there are various uses for pure glycerin, the increase in demand for biodiesel has resulted in the production and stockpiling of large quantities of crude glycerin. This trend is expected to continue.
- Currently there is a need for effective combustion systems for the disposal and heat recovery of glycerin. The most effective glycerin combustion systems typically require a substantial amount of combustion enhancer (an alternate fuel source) to be added to the glycerin in order to achieve the complete combustion of the glycerin. This adds significant cost to the process.
- Existing burners cannot burn pure glycerin because the combustion air speed produced by conventional burners exceeds the flame propagation speed of the air-glycerin mixture. Even if one is able to instantaneously ignite the air-glycerin mixture the flame will be quickly blown away by the burner. This phenomenon is a major obstacle to the development of effective glycerin combustion systems.
- Accordingly, it would be desirable to have a glycerin burning system which is not costly to operate and is capable of completely combusting a feed of crude or pure glycerin.
- The present invention comprises a glycerin burning system having a specialized atomizing burner capable of combusting a continuous feed of crude or pure glycerin. The burner includes a two-fluid mixing nozzle or a one fluid impingement nozzle. The nozzle has an internal distributor which mixes two fluid feed streams (glycerin and air) as the fluids are expelled through an orifice. The distributor has channels which cause the air to swirl before mixing with the glycerin. An impingement pin is provided outside the orifice to diffuse the mixture and reduce combustion air speed.
- To improve performance, the burner's air feed line exchanges heat with the combustion chamber to preheat the air passing through the feed line before the air is mixed with the glycerin. In addition, a flame retention head is employed on the burner to improve combustion efficiency. Alternate air diversion methods are also proposed for reducing combustion air speed.
- In the preferred embodiment, the combustion chamber is first heated to a designated operating temperature by combusting a mixture of glycerin and alcohol before switching to a feed of pure raw glycerin. Upon cessation of combustion operations, the system is purged with water.

glycerin burning system 10 is illustrated inFIG. 1 .Glycerin burning system 10 may be used to burn a continuous feed of raw or pure glycerin.Glycerin burning system 10 generally includesburner 20 which expels glycerin throughnozzle 22 intocombustion chamber 12 where the glycerin is combusted incombustion zone 78. Exhaust gases are vented to the atmosphere throughexhaust 26. Air is fed to burner 20 by a burner air blower and a portion of the air fed toburner 20 is diverted intoconduit 18 which wraps aroundwall 14 ofcombustion chamber 12.Conduit 18 may be the interior region of a “jacket” surroundingwall 14 or any other conduit suitable for directing the flow of air aroundcombustion chamber 12 while allowing the air to exchange heat withcombustion chamber 12.Ports wall 14 and direct heated air towardcombustion zone 78. The direction of hot air towardscombustion zone 78 serves two synergistic functions. First, the hot air helps atomize the glycerin expelled fromburner 20. Second, the air flow reduces the effective air velocity ofair exiting burner 20. These two functions work together to mitigate “flare out.” Flare out occurs when the combustion air velocity exceeds the flame propagation speed in the glycerin-air mixture. -
FIG. 2 illustratesburner 20 in greater detail.Burner 20 includesfuel pump 28 which pressurizes the glycerin feeding intoburner 20. During glycerin combustion operations, glycerin passes through fuel cutoff solenoid 30 (when in the open position) throughcheck valve 40 intomanifold 46 where it is fed to fuel feed line 38.Ignition transformer 44 provides a spark to ignite the fuel after it exitsnozzle 22 and strikesimpingement pin 34.Starter feed 50 is provided for supplying a feed of a starter fuel (such as alcohol or an alcohol-glycerin mixture) to burner 20 during start-up. The starter fuel is used to heat the combustion chamber to a designed operating temperature before switching to a pure glycerin feed. The starter fuel is supplied to fuel feed line 38 thoughcheck valve 48 andmanifold 46. An exterior pump is used to supply the starter fuel toburner 20. - Water is used to purge
burner 20, thus cleaning the internal components thereof, upon the cessation of combustion operations. Water is supplied toburner 20 thoughwater feed 52. Purgefluid solenoid 42 regulates the flow of water toburner 20. Like the starter fuel, an exterior pump supplies water towater feed 52. - Air is supplied to
burner 20 by a burner air blower. As mentioned previously, a portion of this air feed is directed into the conduit wrapping around the combustion chamber. The other portion is fed intoair tube 32. Turning toFIG. 3 , a portion of the air fed intoair tube 32 is diverted throughvents 54 inflame retention head 36.Flame retention head 36 helps provide a broad, stable combustion air flow to promote even flame propagation. As mentioned previously, the glycerin is expelled throughnozzle 22 where it strikes the tip ofimpingement pin 34, diffuses, and mixes with combustion air. -
FIG. 4 shows a detailed view ofnozzle 22.Nozzle 22 is an internal mix nozzle in which a portion of the combustion air is mixed with the glycerin feed as the glycerin passes throughconduit 58 andorifice 56 and strikes impingementpin 34.Distributor 62 rests insidereceiver 60.Distributor 62, which imparts rotation to the air feed before the air feed begins mixing with the glycerin feed, is shown in greater detail inFIG. 5 .Distributor 62 hasfuel feed connector 64 which connectsdistributor 62 to the fuel feed line of the burner. Fuel passing through the feed line passes throughconduit 66 withindistributor 62 and outorifice 72. Air passes arounddistributor 62 throughchannels 68 intoswirl channels 70.Surfaces receiver 60 so that air passing arounddistributor 62 is forced throughchannels 68 andswirl channels 70.Swirl channels 70 impart rotation to the air feed by directing the air in angularly about the central axis ofconduit 66. This rotation aids in the mixing and atomization of the glycerin feed as it exits the nozzle. -
FIG. 6 is a section view ofnozzle 22 withdistributor 62 omitted for greater clarity.Glycerin exiting orifice 72 ofconduit 66 is picked up by the rotational air flow passing around distributor. The glycerin passes through conduit and outorifice 56 where it impinges againsttarget surface 80 ofimpingement pin 34. This diffuses the air-glycerin mixture, reflecting a portion of the stream back onto thestream exiting orifice 56. This creates more collision between glycerin and air particles and greater diffusion aroundimpingement pin 34. This also reduced the velocity of the stream. The glycerin and air mixture passes aroundimpingement pin 34 as a fine mist or fog. Such a nozzle design both reduces combustion air speed and atomizes the glycerin feed for improved flame propagation. - With the various components of the glycerin burning system now described, operation of the glycerin burning system will be described in greater detail. During start-up, starter fuel is fed to
burner 20 throughstarter feed 50. The starter fuel passes throughcheck valve 48 and intomanifold 46 before passing through fuel feed 38.Ignition transformer 44 produces a spark as the starter fuel exitsnozzle 22. Starter fuel is fed toburner 20 for a sufficient period of time to heat the combustion chamber to the desired temperature. - When the desired temperature is reached,
fuel pump 28 feeds fuel tomanifold 46 throughcheck valve 40. In order to do this,fuel cutoff solenoid 30 is moved to the open position. The fuel is fed tonozzle 22 where it is atomized and combusted. Checkvalve 48 prevents the fuel from being forced intostarter feed 50. - Upon cessation of combustion operations,
fuel cutoff solenoid 30 is moved to the closed position and purgefluid solenoid 42 is opened. Water or other purging fluid is fed toburner 20 viawater feed 52. The water passes throughpurge fluid solenoid 42 intomanifold 46. The water then passes out ofburner 20 through fuel feed 38 andnozzle 22. This cleans the internal components ofburner 20 andnozzle 22 to insure thatburner 20 andnozzle 22 will last many burning cycles without “gumming up.” Checkvalve 40 andcheck valve 48 prevent the purge fluid from passing back into the fuel and starter fluid feed lines. - The preceding description contains significant detail regarding the novel aspects of the present invention. It should not be construed, however, as limiting the scope of the invention but rather as providing illustrations of the preferred embodiments of the invention. For example, components of the present invention, such as
nozzle 22, may be useful in other applications. Thus, the scope of the invention should be fixed by the following claims, rather than by the examples given.
