    Abstract: A system for producing superior quality synthesis gas (“syngas”) consisting of a series of chambers in which the gasification stages of reaction, homogenization and activation occur. The first stage reaction stage agitates and combines the reactants, consisting primarily of organic matter, oxidizer and steam, to initiate gasification of the organic and volatile fraction and to transport the inorganic residue to continuous removal. In the homogenization chamber, turbulence is induced by injecting gaseous species. The gas mixture emerging from the homogenization chamber is accelerated via a third stage communicating duct and is introduced tangentially into the fourth stage activation chamber inducing a cyclonic motion wherein a high intensity radiant heat source is introduced along the central axis of the gas vortex.

  • Patent number: 9074152
    Abstract: A plasma-assisted waste gasification system and process for converting waste stream reaction residues into a clean synthesis gas (syngas) is disclosed. The feedstock is fed into a reactor roughly one-third from the bottom through the use of a feed mechanism. The reactor has three zones; a bottom zone where melting occurs, a middle zone where gasification takes place, and a top zone with integrated plasma torches to control the temperature and polish the syngas. The residence times in the three zones are selected to optimize the syngas composition and melted products. The syngas leaves the reactor and is partially quenched with relatively cooler synthesis gas. The partially quenched syngas is further cooled to recover heat for steam generation and/or preheating the waste stream to the reactor. The cold syngas is then processed to remove pollutants. The clean synthesis gas is combusted in power generation equipment to generate electricity, or converted to other fuels by chemical processes.

    Abstract: Conventionally, sugarcane processing avoids leaving residual sucrose in the bagasse, since the bagasse will be burned and the value of the sucrose would be lost. However, when coupled with a Green Power+® process to extract hemicelluloses, sucrose may also be extracted and recovered from the bagasse. In some variations, a process includes mechanically treating a feedstock to generate a sucrose-rich stream and lignocellulosic material that intentionally retains a significant amount of the initial sucrose in the feedstock; extracting the lignocellulosic material with steam and/or hot water to produce cellulose-rich solids and an extract liquor containing hemicellulosic oligomers and sucrose; and then hydrolyzing the hemicellulosic oligomers into a hemicellulose sugar stream. Each of the sucrose-rich stream and the hemicellulose sugar stream (containing the starting residual sucrose) may be recovered or further processed (e.g., fermented to ethanol).

In a first mode of operation the gas (30) is passed through the chamber (2) at a first velocity. The apparatus comprises a means (20, 21) for temporarily increasing the velocity of the hot gas (30) such that in a second mode of operation the velocity of the gas (30) exiting the means (20, 21) is temporarily increased.

    Abstract: A method for efficiently conveying impurities in a pressurized fluidized incinerator system is provided. Cleaning gas is supplied to an upper valve, and thereafter, the upper valve is driven so as to communicate an upper discharge device and a tank. The upper discharge device is driven so as to convey the impurities from the dust collector to the tank, and thereafter, the upper discharge device is stopped and the upper valve is driven so as not to communicate the upper discharge device and the tank. Thereafter, the supply of the cleaning gas to the upper valve is stopped.

  • Publication number: 20150040808
    Abstract: Is provided a method for starting up a pressurized fluidized bed incinerator system by which cracking of silica sand as a bed material can be prevented at low costs. By heating the silica sand as the bed material filled up in a bottom portion of a pressurized fluidized bed incinerator, a temperature of a freeboard of the incinerator is heated, and after the temperature of the freeboard is heated to 750 to 900° C., a material to be treated having a water-containing organic substance is fed to the pressurized fluidized bed incinerator.

  • Publication number: 20150034530
    Abstract: Described herein is a process that employs heat, derived from the combustion of product cleaning streams, such as waste streams, in a solvent-based extraction process. Solvent extraction of bitumen generally involves combining solvent with a bituminous feed to produce a cleaned bitumen product. Solvent is recovered, for example by utilizing heat to cause evaporation, and recovered solvent may be re-used. In an exemplary embodiment, hot flue gas from waste stream combustion may provide the heat to evaporate the solvent. Product cleaning waste streams may be ones produced from the trim cleaning of solvent extracted bitumen or from treatment of bitumen froth produced in a water-based extraction process. The heat generated can contribute to the energy requirements of the overall solvent extraction of bitumen.

    Abstract: A precombustor system (300) including an ignition chamber (301) having a front wall (308), a central axis, a diameter Dic, and an outlet (313) configured to discharge a product gas (315). The ignition chamber (301) includes a central ignition oxygen injector (307) configured to inject a first oxygen stream from the front wall (308) substantially parallel to the central axis, and a tangential primary fuel injector (303) configured to inject a primary fuel stream tangential to the central axis at a location an axial distance Xpf downstream of the front wall (308). The ratio Xpf/Dic is from 0.25 to 4.0. The central axis forms an angle a with a vertical line of less than or equal to about 45 degrees. The trajectory of the primary fuel stream forms an angle ? with a plane that is perpendicular to the central axis of less than or equal to about 20 degrees. A method for combustion is also disclosed.

  • Publication number: 20140352582
    Abstract: The present invention provides a biomass combustion burner applied to a pulverized coal-fired boiler to burn biomass fuel, a biomass-mixed fired boiler that reduces an amount of CO2 derived from fossil fuels, and a method for burning biomass fuel using the foregoing. The biomass combustion burner includes a biomass fuel jet nozzle having a fuel jet port that jets biomass fuel conveyed by primary air; a secondary air nozzle having a secondary air jet port that surrounds the fuel jet port; and a tertiary air nozzle having a tertiary air jet port that surrounds the secondary air jet port. The biomass fuel jet nozzle includes a fuel concentration adjusting section that changes a biomass fuel stream into a swirl flow to thereby make a fuel concentration higher on an outer circumferential portion side; and a degree-of-swirl adjusting plate that reduces a degree of swirl of a jetting fuel stream.

  • Publication number: 20140338576
    Abstract: A Novel fuel object comprised of a proportion of corn stover and a proportion of wood fiber combined with a basically reacting compound. The object comprises fiber of the appropriate size and moisture content combined with an inorganic base. An appropriately sized object is readily manufactured, provides high heat output, is consistent in fuel characteristics, and is sized and configured for use in power generation facilities. Based on fiber selection and processing, the fuel object may be used in a variety of current power generation technologies including stoker, fluidized bed, gasifier, cyclonic, direct-fired, and pulverized coal technologies, and results in significant reduction of air emissions (including sulfur dioxide, nitrogen oxides, hydrochloric acid, carbon monoxide, carbon dioxide, and mercury) compared to coal with no loss of boiler or furnace efficiency.

  • Patent number: 8881662
    Abstract: An inside of an incinerator body into which sludge is fed is divided into a lower portion, a portion above the lower portion, and a top portion in a height direction. The lower portion serves as a pyrolysis zone for supplying fluidizing air having an air ratio of 1.1 or less together with fuel to thermally decompose the sludge while fluidizing the sludge. The portion above the lower portion serves as an over bed combustion zone for supplying only combustion air having an air ratio of 0.1 to 0.3 to form a local high temperature place to decompose N2O. The top portion serves as a perfect combustion zone for perfectly combusting unburned contents. The quantity of N2O generated during sludge incineration can be drastically reduced while maintaining the use quantity of auxiliary fuel at the same level as that of a conventional incineration method.
