Description

FIELD OF THE INVENTION

The following invention is generally related to instrumentalities and methodologies in combustible fuels. More specifically, the instant invention is directed to a method and apparatus for a combustible fuel that is easily lit by an external ignition source and is resistant to deterioration of effectiveness, thereby having a long shelf life.

BACKGROUND OF THE INVENTION

Many efforts have been made to produce fuels for barbecuing that are clean-burning, easy to handle, and easily ignitable. Charcoal, usually made from a wood base, is the most common component of fuels for barbecuing. Charcoals having vegetable and coal bases have also been used. Such fuels are difficult to ignite for cooking and often require the use of an ancillary flammable material, such as lighter fluid or newspaper, to create a flame of sufficient duration for the charcoal to ignite.
Previous innovations have involved the impregnation of charcoal with a more flammable compound, such as lighter fluid (or other volatile fluids, such as higher alkanes), waxes, or other oxidants that burn faster and more readily than charcoal. These penetrate only the outer surface of the charcoal. Those including volatile components or that are very easily oxidized are susceptible to dissipation over time, greatly reducing the effectiveness of those fuels. Other processes create a mixture of charcoal and an ignitable material, ultimately forming a homogeneous material that, overall, should be easier to burn. The point, however, of utilizing easily ignitable material is to achieve the initial burning of the charcoal. Once the charcoal reaches a certain level of combustion, it burns without further aid. Mixing the ignitable component throughout the fuel adds little overall benefit, because the benefits of ancillary ignitable components are superfluous once the combustion of the charcoal is underway. The use of volatile or easily combustible components throughout such fuels produces fumes during combustion, which may impart undesirable flavors to food cooked using such an article. Such fumes would be given off during the entire burning time, which is a considerable drawback to these types of fuels.
Another consideration for combustible fuel is efficient burning. Some fuels release a very large amount of heat during the initial stages, which tapers off to a much lower release rate during the time appropriate for cooking. It would be more efficient, and perhaps safer, to have a fuel whose heat release rate during ignition was less than the release rate during the optimal cooking time. In this way, the heat generated by a fuel would not be wasted in the startup process, but could be utilized in the form of longer cooking times.
By way of example, one commercially-available charcoal-based fuel exhibits the heat-release profile shown in FIG. 1. The graph depicts the rate of heat release per area of material. The graph peaks at 300-350 kilowatts per square meter during ignition of the material, dropping to a steady-state heat-release rate of approximately 40-50 kilowatts per square meter. This represents an initial ignition stage in which a large amount of heat is released very quickly before the release rate ramps down to a state in which cooking is appropriate.

The following prior art reflects the state of the art of which applicant is aware and is included herewith to discharge applicant's acknowledged duty to disclose relevant prior art. It is stipulated, however, that none of these references teach singly nor render obvious when considered in any conceivable combination the nexus of the instant invention as disclosed in greater detail hereinafter and as particularly claimed.

Kim teaches a three-layer combustible fuel article, comprising three distinct layers: a fire-igniting layer, a fire-catching layer, and a body layer. The body layer contains carbonized wood and a starch binder, and the other layers include less carbonized wood and more easily-ignitable components. Also included are optional air holes and optional grooves for visual appeal. Inter alia, Kim specifically recites that “No coal is used in the combustible articles.” (col. 2, line 12).
The remaining citations diverge even further from the nexus of the instant invention.

SUMMARY OF THE INVENTION

The present invention addresses all of the most pervasive problems regarding charcoal-type fuels. In its essence, the present invention is embodied in a freestanding fuel article whose top surface is coated with an accelerant comprising barium nitrate and sodium nitrate, and in a method for making such a fuel article. The body comprises a homogeneous mixture of wood charcoal, anthracite coal, and a starch binder, and contains regularly-spaced vents that extend though its entire thickness. One of these vents is centrally located and of a cruciform shape. Above this vent is a fuse or lighting tab made out of a combustible material. Each fuel article is individually wrapped until use, preventing any dissipation of ignition materials during periods of nonuse. After initial ignition, the fuel is ready for cooking in less than five minutes.
The fuel is made by creating mixtures of the body portion and of the accelerant, and then introducing them successively into a forming device, compacting between each step. The vents are formed during the compaction step. The fuel is ejected from the forming device and then dried in a heated environment to remove any excess water from the mixture. The surface of the fuel is smoothed, the fuse or lighting tab is applied, and the fuel is then packaged, first individually, and then in groups better suited to larger cooking apparatus.
When the fuse or tab is lit, ignition is forced at the centrally-located vent. This vent has increased surface area due to the corner edges inherent in its shape, allowing quicker and more efficient ignition. The ignited area in the center of the fuel spreads out across the entire coating of accelerant, which includes some of the surface area extending down into the top of each vent. By the time the accelerant is entirely consumed, the body has ignited and continues to burn. The vents through the body allow air to circulate and produce a chimney effect, and also provide preferential burning sites due to their greater surface area. This air circulation allows the body to burn evenly and more completely during its steady-state combustion period than if air circulation were not allowed. The concentration of accelerant at the top of the fuel directs the steady burning of the fuel from the top down.
The addition of anthracite coal to the body composition produces a cleaner-burning fuel than a pure charcoal fuel. The homogeneous dispersion of wood charcoal throughout the coal in the present invention provides a catalytic effect, allowing the coal to burn more easily than it would without the addition of charcoal. Additionally, the fuel according to the present invention has a much lower heat release rate than conventional charcoal fuel articles during the ignition stage, and the heat-release rate is lower during the ignition stage than during the steady-state cooking stage, both of which translate to longer burning times. The heat steady-state heat-release rate and the steady-state burning temperature of the fuel according to the present invention are also higher than that of commercially available charcoal fuel articles.
Compare FIG. 1, the profile of a commercially-available fuel material, described above, with FIG. 2, the profile of the fuel according to the present invention. At the ignition stage, the heat-release rate peaks at approximately 45-55 kilowatts per square meter before briefly dropping, and then increasing to its steady-state rate of approximately 60-65 kilowatts per square meter. This represents a lower release of energy during ignition, which translates into a longer burning time.

DESCRIPTION OF PREFERRED EMBODIMENTS

Considering the drawings, wherein like reference numerals denote like parts throughout the various drawing figures, reference numeral 10 as shown in FIG. 9 is directed to the fuel article according to the present invention.
Referring to FIG. 3, the flow chart associated with the method of the present invention can be explored. Initially, each component of the fuel is in a separate container. A computer is used to measure and dispense the proper amount of each component into an appropriate mixing tank. The wood charcoal, anthracite coal, sodium nitrate, and barium nitrate are dry, and the binder mixture is starch preferably combined with water. In one tank, charcoal, coal, and the binder mixture are combined to produce a body mixture, preferably to the consistency of a viscous paste. In a second tank, charcoal, coal, sodium nitrate, barium nitrate, and the binder mixture are combined to produce an accelerant mixture. The amount of liquid present in the accelerant mixture may be varied to produce optimal results, as will be explained later in the process.
Referring now to FIGS. 4-8, the construction and operation of the molding device 30 used to form the fuel article 10 can be explored. The molding device 30 has a sleeve 32, to which is attached a base plate 34, preferably a solid plate. The base plate 34 is attached by a pivot to one end of the sleeve 32 such that the base plate 34 pivots outwardly from the sleeve 32, but in the same plane as the opening in the sleeve 32. At the other end of the sleeve is oriented a piston 36 containing shaped rods 38. The rods 38 preferably form and define vents in the fuel article 10, depicted in FIGS. 9-12 as a centrally-located cruciform-shaped aperture 12, with peripheral circular bores 14 and peripheral elongated slots 16, arranged in an alternating pattern extending radially outward from the centrally-located cruciform-shaped aperture 12.
The molding device 30 is loaded (FIG. 4) with the body mixture to form the monolith 2 that comprises the long-burning body portion of the fuel. The mixture is compacted with the piston 36 (FIG. 5). The rods 38 attached to the piston 36 extend through the mixture to form the venting holes 12-16 in the fuel article 10, the shapes of the venting holes 12-16 corresponding to the various shapes of the rods 38. After the piston 36 is retracted, the accelerant mixture is introduced (FIG. 6) into the molding device 30. The viscosity of the accelerant mixture will determine the extent to which the accelerant penetrates the monolith 2 and the extent to which accelerant is coated within the venting holes 12-16 of the finished product. The piston 36 is again engaged (FIG. 7) for compacting, and the shaped fuel article 4 is then ejected (FIG. 8) through the end opposite of the piston 36, the exit path created by pivoting the base plate 34 outwardly from the sleeve 32.
The shaped fuel articles 4 are then loaded into drying trays, which are put into a kiln for drying. The kiln is preferably tunnel-shaped and extends approximately 40-50 meters. The entrance temperature of this kiln is approximately 150° C., and the air is dry. This atmosphere is maintained for 6.5 to 7 hours, at which time they are removed. The exit temperature is a very moist 50-60° C. The fuel article is then smoothed, and a fuse 18, formed as a substantially circular disc of fibrous material, is attached on a surface which had received the accelerant mixture. The fuse 18 is centrally-located on the fuel, above the cruciform-shaped aperture 12. The fuel article 10 is then packaged in a protective layer 20, preferably plastic shrinkwrap. After each fuel article 10 is individually encased, as shown in FIGS. 10-13, a set of six fuel articles 25 (each individually wrapped) is arranged in a circular orientation, and the unit is wrapped as a set in a second protective layer 20, as in FIGS. 14-15.
The finished fuel article 10 is cylindrically-shaped. Referring to FIG. 11, the cross section of the short axis of the article 10 is preferably defined by a circle from which two portions have been excised. The excised portions are defined by two planes 22 coincidental with two chords of the circle. The planes 22, when extrapolated, form an included angle of approximately 30°. This angle permits orientation of six such articles to define a circle about a center portion which is free of the cooking medium. This center portion of the circle is the optimal area for cooking. If food is cooked over this center portion, drippings from the barbecued item will not drip onto the coals and produce smoke or other undesirable effects which tend to adversely affect the flavor of the barbecued item. Cooking directly over the fuel article 10 subjects the barbecued item to greater heat overall, which leads to greater cooking control when using fuel articles of the present invention.
The accelerant mixture includes barium and sodium nitrates, which are oxidizers that serve to ignite the body portion of the fuel article 10. When the accelerant mixture is applied and the resulting mass compacted, the accelerant mixture flows into the venting holes 12-16. The degree to which the inside surface is coated is directly related to the viscosity of the accelerant mixture. This process produces zones of designated accelerated heating, which include the accelerant-covered top surface, the profile of each of the venting holes 12-16 in the accelerant-covered surface, and the circumscribing peripheral walls of the fuel article 10. Thus, the function of the centrally-located cruciform-shaped aperture 12 is to provide a surface that is more conducive to ignition than the rest of the fuel article 10. Ignition at the centrally-located cruciform-shaped aperture 12 is preferable due to the increased surface area provided by the several corners defined inside the vent. These areas are more conducive to ignition than any other area of the fuel article 12, having a greater surface area relative to its size. After ignition at the center, burning of the accelerant coating continues radially outward, due to the substantially even coating of the accelerant provided by the method of the present invention. When the burning contacts the peripheral venting holes 13-16, a similar phenomenon occurs, providing uniform burning by virtue of the substantially even spacing of the venting hold 13-16. Because all of the venting holes 12-16 extend through the entire fuel article 10, enhanced airflow is provided, encouraging even top-to-bottom burning of the fuel article 10. the inclusion of anthracite coal in the body of the fuel article 10 provides cleaner burning than charcoal alone, which is also useful in avoiding off-flavors and odors in the barbecued item.

The following table reflects the general ranges for both the accelerant components and body components. The table also reflects the preferred formulation for a specific briquette.
