    Abstract: A reformer furnace having a reaction space formed with reaction tubes, a firing space fitted with burners and a flue gas channel in fluid connection with the firing space. The burners are arranged at a first end face of the reformer furnace and produce flames oriented towards a second end face to fire the reaction tubes. The flue gas channel has a transition region and a withdrawal region, wherein the flue gas channel is connected to the second end face of the firing space via the transition region and the transition region of the flue gas channel has a reduced channel diameter compared to the withdrawal region of the flue gas channel. The transition region has a constriction relative to the withdrawal region which results in a hydraulic decoupling between the firing space and the withdrawal region of the flue gas channel.

  • Patent number: 11754315
    Abstract: A gas manifold allows each distribution chamber to be fed with fuel gas at an appropriate flow rate irrespective of an increase in the number of distribution chambers included in the gas manifold. Fuel gas flowing through in an inlet is distributed to a plurality of distribution chambers through a main channel. A bypass channel parallel with the main channel also feeds fuel gas to a maximum distribution chamber. This can prevent the feeding of the fuel gas to the maximum distribution chamber from being affected by and reduced by the feeding of the fuel gas to the bypassed distribution chambers. This also prevent the feeding of the fuel gas to the other distribution chambers from being affected by and reduced by the feeding of the fuel gas to the maximum distribution chamber. The plurality of distribution chambers are thus fed with fuel gas at appropriate flow rates.

    Abstract: gasifier and a gasification process provides a long, uniform temperature zone in the gasifier, regardless of the particle size, chemical composition, and moisture content of the fuel by sandwiching a reduction zones between two oxidation zones. The gasifier and gasification process produces a char that is more energy-dense and almost devoid of moisture, affording an additional (char) oxidation zone with a temperature that is higher than a first oxidation zone which is closer to an evaporation and devolatilization zone. As such, the additional (char) oxidation zone contributes to augmenting the reduction zone temperature, providing a favorable dual impact in improving syngas composition and near-complete conversion of the tar.

  • Patent number: 7635456
    Abstract: A syngas reforming reactor has a shell-and-tube configuration wherein the shell-side fluid flow path through the tube bundle has a longitudinal configuration. The reactor can include a shell-side inlet fluid distributor plate below the lower end of the tube bundle, and a flow sleeve in an enlarged-diameter discharge annulus at an upper end adjacent the tube sheet to prevent short-circuiting of the shell-side fluid into the shell-side fluid outlet. The tube bundle can include a plurality of ring baffles and lattice baffles. The longitudinal flow configuration can provide a lower shell-side pressure drop and lower cost compared to a conventional cross-flow reforming exchanger.

  • Patent number: 7632471
    Abstract: A reaction furnace utilizing high-temp steam and recirculated heat source to separate mercury and crack dioxin and organic substances contained in waste includes a first combustion chamber having a burner for producing high-temp hot gas, which is sent to a second combustion chamber for heating a reaction chamber and a high-temp steam generator therein. High-temp steam produced by the high-temp steam generator is introduced into the reaction chamber for decomposing or distilling waste being treated. Gas mixture produced in the reaction chamber is discharged to a gas mixture treatment system for separation. Fuel gas and fuel oil separated from the gas mixture are introduced into the burner for producing the high-temp hot gas, and waste water separated form the gas mixture is led to the high-temp steam generator for producing the high-temp steam. And, soil in the waste that has been treated is discharged via a discharge outlet.

  • Patent number: 7622087
    Abstract: A reactor air supply system including a first air inlet configured to receive air supplied from a first air supply. The system includes a burner having a burner nozzle configured to discharge fuel for mixing with the first air and configured to ignite the fuel/air mixture. A second air inlet is provided that is configured to receive heated air supplied from a second air supply, and a duct is provided to receive the ignited fuel/air mixture and the heated air supplied from the second air supply. The duct has an outlet configured to connect to a reactor. The duct is configured to receive the heated second air such that the heated second air mixes with the ignited fuel/air mixture at a location downstream of the burner.

  • Patent number: 7582269
    Abstract: A subsurface thermally autogenous reactor and method has downgoing and upgoing flow passages connected at the bottom to form a U-tube and in heat exchange relation to each other. The downgoing and upgoing flow passages each have an upper heat exchange section and a lower reaction section. An air injection system injects air into the downgoing flow passage between the heat exchange and reaction sections. The cross sectional area of the upgoing heat exchange section is greater than the cross sectional area of the downgoing heat exchange section to balance the downgoing and upgoing flow velocities. The downgoing heat exchange section has multiple tubes to increase the heat transfer area.

  • Patent number: 7550063
    Abstract: The invention relates to both a method and apparatus for thermal cracking hydrocarbons. The apparatus includes a rotating conical drum assembly within a vessel containing a hydrocarbon feedstock. The conical drum assembly is internally heated to cause cracking of hydrocarbons adjacent the conical drum surface and the formation of coke on its external surface as the conical drum rotates. Coke is removed from the drum surface by a coke removal system and cracked hydrocarbon product is collected as a vapor.
