  • Publication number: 20150079259
    Abstract: An apparatus and method for cooking, heating, or drying in which, as items or materials are conveyed through a heating chamber by a linear, spiral, or other type of conveyor, hot combustion product gases are delivered upwardly through an upwardly extending first annulus or other flow gap which is closest to the conveyor. The hot combustion product gases are then delivered downwardly through the heating chamber into contact with the items or materials on the conveyor. Next the combustion product gases are delivered from the lower portion of the heating chamber into the lower portion of a second annulus or other flow gap or passage. The second flow gap or passage is separated from the heating chamber by the first annulus or other flow gap. Subsequently, the combustion product gases are delivered upwardly through the second flow gap or passage.

  • Publication number: 20140000535
    Abstract: A metallurgical plant has a plant positioned upstream of a steel-generating plant and has a gas-generating plant which generates an export gas. Carbon dioxide and/or water contained in the export gas is removed from the export gas in a separation device. A resulting product gas is heated, before being supplied to the upstream plant, in a firing unit through the combustion of a heating gas. Excess thermal energy produced during the combustion of the heating gas which is not used for heating the product gas is thermally utilized. The utilization may take place within the firing unit through steam generation and/or downstream of the firing unit to preheat the heating gas and/or an oxidation gas used for the combustion of the heating gas and/or through the pre-heating and/or drying of raw materials to be supplied to the upstream plant and/or to the gas-generating plant.

  • Publication number: 20100212180
    Abstract: One embodiment of the present invention discloses a process for reducing water content in wood material. The process includes the steps of: feeding the wood material into an overheated vapour filled, oxygen free drying apparatus; indirectly overheating the vapour in the drying apparatus by heating devices, whereby water and other chemical substances vaporise from the wood material into the atmosphere within the drying apparatus; releasing surplus drying apparatus vapour into separation devices which are connected to the drying apparatus; and discharging the dried wood material from the drying apparatus when the moisture content in the wood material has reached a level of less than 10% by weight. One embodiment of the present invention also discloses wood material drying devices to be used in the process.

  • Patent number: 6742283
    Abstract: Method for drying wood in a short period of time by maintaining the concentration of a combustion gas contained in a drying room atmosphere for use in drying the wood to a high value and by maintaining the pressure of the drying room atmosphere to a high value. Wood fuels such as waste wood are put into a combustion chamber ins lower area of a combustion gas generating furnace and then the wood fuels are burned, followed by introducing the high-temperature combustion gas generated by the burning of the wood fuels into an upper area of a drying room housing the green wood to thereby dry the wood. Thermal drying of the wood is carried out by maintaining the concentration of the combustion gas present in the drying room atmosphere at a the high value and by maintaining the pressure of the drying room atmosphere at a high value.

  • Patent number: 6138381
    Abstract: A process of treating moist fuel, particularly biomass fuel, in connection with a power production process, comprises drying moist fuel (7) by means of combustion air (3), which is thereafter supplied to the power production process combustion section (1). Flue gas (11) from the combustion section, which as a result of said drying has become moisture-laden, is condensed (13) while recovering heat (15), which may be used as drying heat. In accordance with a preferred embodiment, the flue gas condensation is used to humidify (31) the combustion air.

  • Patent number: 5966837
    Abstract: The device relates to a wood drying plant comprising a wood drying device and a purifying device which is arranged to receive a drying gas from the wood drying device, the drying gas comprising water steam and volatilized organic components such as terpenes, and to purify the drying gas from organic components and to recover the latter. The purifying device comprises at least one condenser which is arranged to separate relatively difficultly volatilized components containing organic components and relatively easily volatilized components. The purifying device also comprises a separating device which is arranged to separate said organic components and a rest material from the relatively difficultly volatilized components. The purifying device also comprises a transferring device which is arranged to transfer organic components present in the rest material to the drying gas introduced in the purifying device.

  • Patent number: 5881475
    Abstract: This method relates to a non-draining type human waste disposal by pulse combustion drying. In the method, a pulsating combustion gas is discharged downward into a vertically cylindrical dryer from a pulse combustor disposed at the top of the dryer, and making contact the pulsating combustion gas with residue-removed human waste, digester chamber sludges or their mixtures charged therein, turning the charged matters to dried powder and steam under the dryer conditions of 120.degree.-150.degree. C., withdrawing the dried powder from the bottom of the dryer and the combustion gas containing steam from a lower side of the dryer, dust-removing the combustion gas containing steam maintained at 120.degree.-150.degree. C., deodorizing the dust-removed combustion gas, and exhausting the deodorized gas into the air. As an alternative method, the dried powder and the combustion gas containing steam are withdrawn from the bottom of the dryer, the withdrawn material maintained at 120.degree.-150.degree. C.

  • Patent number: 5483754
    Abstract: The invention relates to the heat treatment of continuously moving length of textile material in a treatment apparatus with at least two successive treatment zones by means of hot gas. After it has been heated, all of the exhaust gas from the first treatment zone is introduced into the second treatment zone as fresh gas. An exhaust gas branch stream drawn off at the end of the second treatment zone is afterburned. The exhaust gas branch stream which has been heated in this way first of all preheats the second exhaust gas branch stream coming from the second treatment zone, and before being discharged into the atmosphere the exhaust gas branch stream coming from the first treatment zone and the fresh air air heated. In this way extremely economic operation of the entire treatment apparatus is provided, with reliable purification and disposable of the exhaust gas.
