Abstract: The quality of the briquettes granulated by a briquetting machine is improved. A briquetting machine control device samples the briquette that have been produced to measure an apparent density and a crush strength of the sampled briquette (step S10), and controls each operation set value adjusting unit (4, 6, 7) of the briquetting machine so that the actual measurement values come closer to predefined briquette quality target values (step S20 to step S60).

Abstract: Systems are disclosed for direct conversion of a used or waste material into a burnable fuel and to burnable fuels derived therefrom.

Abstract: Coal compacts which are suitable for coking in coke oven chambers are prepared by pressing and compacting coal in a pressing device having a design which shapes the surface of the coal compacts to provide higher surface area. Already compacted coal blocks can be pressed to generate the surface shape. The resulting coal compacts exhibit significantly improved properties during the coking process, resulting in improved gas and heat exchange. A device for compacting coal preferably contains a plate provided with shaping elements on the pressing surface.

Abstract: A biomass-based fuel pellet, such as a fuel pellet which includes thermoplastic polymeric material and a substantial amount of cellulosic material, e.g. cellulosic material derived from biomass source(s), is provided. The fuel pellet commonly includes about 5 to 15 wt. % of the thermoplastic polymeric material and at least about 75 wt. % cellulosic material. Optionally, the fuel pellet may comprise a lignin additive. Many embodiments of the fuel pellets are suitable for use in a coal-fired furnace and/or in other industrial boiler applications.

Abstract: According to the invention, unpurified biodiesel is brought in contact with cellulose-containing material by continuously and/or discontinuously mixing the same in order to eliminate the glycerin and catalyst residues, such as potassium soaps, accumulated during the production of the biodiesel. A system for carrying out said method comprises an agitated sedimentation tank (1) with a conduit (4,5) for delivering purified biodiesel into the agitated sedimentation tank (1) and a conveying device (6) for feeding cellulose-containing material into the agitated sedimentation tank (1). A drive unit (51) for an agitator (50) is disposed in the agitated sedimentation tank (1). A conduit (16, 20) extends from the agitated sedimentation tank (1) to at least one static sedimentation tank (2, 3). A valve (13) via which solid matter can be discharged from the agitated sedimentation tank (1) is mounted in the area of the bottom of the agitated sedimentation tank (1).

Abstract: A device for producing fodder and/or fuel by pressing vegetable materials, having a matrix shaped as a ring with axially laid out channels having a circular cross-section onto the mouths of which fits at least one rolling-off body, with the channels including the conical entering/tapering end connected to the mouths and the linked up cylindrical channel section of channels, with the conical entering/tapering end length being equal to from about 15% to about 30% of the total channel length. On the lower averted side of the matrix, from the conical entering/tapering end of channels, at least one additional matrix has axially laid out channels with identical cross-section placed in an exact alignment with the channels of the matrix, and the matrix is connected with a minimum of one additional matrix in a way in which the assembly can be dismantled or knocked down.

Abstract: An organically clean biomass fuel formed of mixture of a powder, which may be either dried, cellulosic product, wood charcoal powder, and/or a combination of the two, and a fluid, which may be vegetable oil, vegetable alcohol or a combination of the two. A centrifugal machine dries moist, cellulosic product and extracts black liquor. A grinder transforms the dried, cellulosic product into powder. Gum may be extracted from the vegetable oil or vegetable alcohol. A batch mixer or vibrating vessel mixes the powder and the fluid together; the fluid moisturizes the powder. Depending upon the relative amount of the fluid as compared to powder, the mixture will either be in a liquid cream state or a doughy state. If the latter, the mixture may be pressed into briquettes or ingots.

Abstract: Mechanically and biologically stable briquettes and pellets are obtained from either municipal solid waste (MSW), Refuse Derived Fuel (RDF) or municipal sewage sludge and their combination for purposes of disposing said briquettes and pellets as fuel in waste-to-energy processes such as the one described herein or to form geometric aggregates with such briquettes for their disposal at landfill sites. The use of binding material is not required whereas fuel additives such as crushed coal and petroleum residues may be added to enhance fuel performance but are not needed to improve waste processing or product stability and mechanical properties.

Abstract: A method and machine for making a new and improved compressed wood fuel pellet. The method comprising the steps of severing a wafer of tree trunk or branch, punching or splitting a small portion along the grain in the wafer, confining each portion across the grain, and then compressing each portion along the grain to form a compressed wood fuel pellet of contiguous wood having a specific gravity of about 1.2-1.4 with a very high efficiency process and machine.

Abstract: This invention is directed to a method and apparatus for forming an aggregate product from particulate material, and in particular for making an aggregate coal product from coal particles. The method involves the steps of 1) loading the coal particles into a mold having an open end and an inner surface defining, in part, a pressurization chamber, the open end of the mold having an outwardly flaring inner peripheral end surface, 2) pressurizing the coal particles within the pressurization chamber such that the coal particles aggregate to form the coal log, and 3) pushing the coal log out of the mold past the flared end surface so that the coal log expands as it passes the end surface. The method may also include the step of maintaining back pressure on the coal log as it is pushed out of the mold. In addition to coal logs, the mold configuration of this invention may be used for making other aggregate products from particulate materials.
