  • Publication number: 20140072917
    Abstract: A system for converting fuel may include a first moving bed reactor, a second reactor, and a non-mechanical valve. The first moving bed reactor may include at least one tapered section and multiple injection gas ports. The multiple injection gas ports may be configured to deliver a fuel to the first moving bed reactor. The first moving bed reactor may be configured to reduce an oxygen carrying material with a fuel by defining a countercurrent flowpath for the fuel relative to the oxygen carrying material. The second reactor may communicate with the first moving bed reactor and may be operable to receive an oxygen source. The second reactor may be configured to regenerate the reduced oxygen carrying material by oxidation.

  • Publication number: 20130244190
    Abstract: An oxygen combustion system includes a boiler to burn fuel using combustion gas composed of oxygen-rich gas and circulating flue gas, a dust remover disposed in a flue through which flue gas discharged from the boiler flows, a second flue leading the combustion gas to the boiler, the combustion gas being made by mixing the circulating flue gas extracted downstream of the dust remover with the oxygen-rich gas, a combustion gas heater exchanging heat between the flue gas flowing between the boiler and dust remover and the combustion gas flowing through the second flue, and a flue gas cooler disposed between the heater and the dust remover to cool the flue gas. A control unit controls at least one of a flow rate and cooling medium temperature of the flue gas cooler such that temperature of the flue gas introduced into the dust remover will be between 90° C. and 140° C.

  • Publication number: 20130199425
    Abstract: Integrated polymeric-ceramic membrane-based oxy-fuel combustor. The combustor includes a polymer membrane structure for receiving air at an input and for delivering oxygen-enriched air at an outlet. An oxygen transport reactor including a ceramic ion transport membrane receives the oxygen-enriched air from the polymer membrane structure to generate oxygen for combustion with a fuel introduced into the oxygen transport reactor.

  • Publication number: 20120227645
    Abstract: Waste is treated by pyrolysis at a temperature of from 400-700° C. and combustion at a temperature of at least 400° C. Off-gases are catalytically oxidized to reduce emissions. The combusting waste is periodically agitated with high-pressure air bursts to disrupt waste in the chamber and promote even and complete combustion. Air is introduced during pyrolysis to promote controlled flow of off-gas to the catalyst and air and/or water is used to dislodge accumulated ash at the end of the treatment process.

  • Publication number: 20100251946
    Abstract: A system, apparatus and method for the combustion of metals and other fuels are provided. The system can include a fuel combustion apparatus including a combustor having a combustion chamber for burning ground particles from a fuel charge, and a fuel supply apparatus for supplying the ground particles. The fuel supply system can include a fuel charge holder assembly to house and store the fuel charge, a grinder assembly including a grinder configured to pulverize the fuel charge to produce a combustible fuel, and a fuel charge linear feed assembly including a piston in contact with the fuel charge to selectively bias the fuel charge into the grinder to control the consumption rate. Exhaust from the combustion chamber can be used in the incineration of radioactive, chemical and mixed hazardous materials, and in the propulsion of a vehicle in both an air or water environment.

  • Patent number: 4643744
    Abstract: Apparatus for ionizing air, for example for feeding to a boiler to act as a catalyst, comprises a closed container (15) which is divided into two chambers (17, 18). Water is fed under pressure to atomizing jets (21,22) which produce a mist inside each chamber. Air is fed by a pump (28) into the first chamber and passes upwards through the mist in that chamber, through an aperture (20) near the top of a partition wall (19) and downwards through the mist in the second chamber. The thus-ionized air leaves the second chamber via an outlet pipe (30) and passes through a demoisturizing coil (31). The water for feeding to the jets is contained in a reservoir (2) at the bottom of a casing (1) in which the container is mounted.
