  • Publication number: 20150027039
    Abstract: The present invention relates to an apparatus and method for drying a biomass or organic material through one or more auger tubes that may be connected in series. Rotation of the augers drives the movement of the material longitudinally through the auger tubes. In addition, the one or more auger tubes are also heated by a hot liquid or water that may be circulated through a jacket(s) surrounding the one or more auger tubes, and a generally longitudinal flow of air or gas through the one or more auger tubes may be caused by operation of a fan or blower. The operation of a dryer apparatus of the present invention may also be monitored and controlled by a computer to optimize or improve drying conditions. Thus, one or more operational parameters of a dryer apparatus may be altered or controlled based on one or more measurements, such as temperature.

The composition includes a mixture of a hydrocarbon fuel and an organometallic soap selected from among several cerium-containing and ferric compounds. The cerium-containing compound or compounds increase the energy released during combustion of the fuel. The ferric compound or compounds coat an interior wall of a combustion chamber of the internal combustion engine to increase the power output of the engine by reducing the accumulation of residues deposited on the interior wall which interfere with the combustion of fuel.

  • Publication number: 20080229656
    Abstract: A reduction in the formation and presence of peroxides in low sulfur diesel fuels is obtained through the combination of those fuels with an organic nitrate combustion improver. The reduction in the amount of peroxides means that the fuel system elastomers will be more durable, as they are not being corroded by as much peroxide formed in the fuel, fuel color durability is improved, fuel stability is enhanced, and fuel sediments are reduced.

  • Publication number: 20080141584
    Abstract: Methods of using a catalyst preburner upstream of a catalyst burner, such as an anode tailgas oxidizer (ATO), in fuel processing applications. The methods prepare a hydrogen containing gas mixture which can be effectively combusted in a single ATO. The catalyst preburner will convert raw fuels into a gas mixture including hydrogen. This hydrogen containing gas mixture then mixes with the required air flow and anode tailgas and off-gas from a pressure swing adsorption unit before being introduced into the catalyst burner. The methods address the start-ups needs of an ATO as well as the requirement that an ATO be able to burn both liquid and gas fuels in a single unit.

  • Patent number: 7341112
    Abstract: A firefighting training fluid (FFTF) comprising a paraffin blend. The blends of paraffins typically have no less than about two carbon atoms and no more than about twelve carbon atoms. The blends of paraffins may possess Reid vapor pressures in the range from about 2 to about 6.5 pounds per square inch. The blends also typically possess an initial boiling point of not less than about 80 degrees Fahrenheit and an end boiling point of not more than about 370 degrees Fahrenheit. The blends burn relatively cleanly and keep emissions of volatile organic compounds, compounds containing sulfur, smoke, particulates, olefins, and aromatics to a minimum. The blend components mixed to create the blends of paraffins are controlled in order to maintain Reid vapor pressure and initial and end boiling points. Oxygenates may be added to an FFTF in order to further reduce smoke emissions.

  • Patent number: 7332002
    Abstract: The present invention is directed to additives for coal-fired furnaces, particularly furnaces using a layer of slag to capture coal particles for combustion. The additive(s) include iron, mineralizer(s), handling aid(s), flow aid(s), and/or abrasive material(s). The iron and mineralizers can lower the melting temperature of ash in low-iron, high alkali coals, leading to improved furnace performance.
