  • Patent number: 10207245
    Abstract: A voltage application device according to the present disclosure includes a voltage application circuit and a control circuit. The control circuit causes the voltage application circuit to alternately repeat a first mode and a second mode. The first mode is a mode that raises a voltage while time elapses, and generates a discharge current by promoting corona discharge to dielectric breakdown. The second mode is a mode that lowers the voltage to cut off the discharge current by causing a load to be in an overload state against the voltage application circuit. This can suppress an amount of ozone generated, while increasing an amount of radicals produced.

  • Patent number: 10107192
    Abstract: Experimental and numerical investigations on an atmospheric diffusion oxy-combustion flame in a gas turbine model combustor are conducted. The combustor is fuelled with CH4CH4 and a mixture of CO2 and O2 as oxidizer. The stability of the oxy-combustion flame is affected when the operating percentage of oxygen in the oxidizer mixture is reduced below 25%. A new 3D reactor design is introduced for the substitution of ITM reactors into a gas turbine combustor. A new oxygen permeation equation model has been developed by fitting the experimental data available in the literature for a LSCF ion transport membrane. The monolith structure design ITM reactor is capable of delivering power ranging from 5 to 8 MWe based on cycle first law efficiency.

  • Patent number: 9797365
    Abstract: A method for controlling a corona ignition system in which a corona discharge is produced at an ignition electrode by exciting a resonating circuit with an AC voltage produced by a high-frequency generator. The AC voltage is adjusted to a target value depending on an operating state of the engine. Combustion onset is determined by evaluating an electrical variable of the resonating circuit and the target value of the AC voltage is reduced by a predefined value following a predefined number of engine cycles or a predefined operating period. The determined combustion onset is evaluated in one or more engine cycles. The target value for the momentary engine operating state is then increased if, by evaluation of the combustion onset, it is found that a predefined requirement is no longer met. Otherwise, the reduced target value is stored as a new target value for the momentary engine operating state.

  • Patent number: 8920158
    Abstract: Sorbent components containing halogen, calcium, alumina, and silica are used in combination during coal combustion to produce environmental benefits. Sorbents such as calcium bromide are added to the coal ahead of combustion and other components are added into the flame or downstream of the flame, preferably at minimum temperatures to assure complete formation of the refractory structures that result in various advantages of the methods. When used together, the components: reduce emissions of elemental and oxidized mercury; increase the level of Hg, As, Pb, and/or CI in the coal ash; decrease the levels of leachable heavy metals (such as Hg) in the ash, preferably to levels below the detectable limits; and make a highly cementitious ash product.

  • Patent number: 8899969
    Abstract: A method and apparatus for combustion in which a pressurized preheated liquid fuel is atomized and a portion thereof flash vaporized, creating a mixture of fuel vapor and liquid droplets. The mixture is mixed with primary combustion oxidant, producing a fuel/primary oxidant mixture which is then injected into a primary combustion chamber in which the fuel/primary oxidant mixture is partially combusted, producing a secondary gaseous fuel containing hydrogen and carbon oxides. The secondary gaseous fuel is mixed with a secondary combustion oxidant and injected into the second combustion chamber wherein complete combustion of the secondary gaseous fuel is carried out. The resulting second stage flue gas containing very low amounts of NOx is then vented from the second combustion chamber.

  • Publication number: 20140335460
    Abstract: A combustion system is provided that includes a fuel nozzle configured to support a combustion reaction, and an electrode positioned to apply an electrical charge to the combustion reaction. A power converter is positioned to receive heat produced by the combustion reaction and to convert a portion of the received heat to electrical energy. A combustion system controller is configured to provide the electrical charge to the electrode, using energy drawn either from the power converter or from a power storage element, depending on an amount of power being produced by the power converter and on a state-of-charge of the power storage element. The controller is further configured to use surplus energy generated by the power converter to recharge the power storage element.

  • Patent number: 8858222
    Abstract: A new approach for igniting an air-fuel mixture in a turbine or other engine is disclosed. Resonance-enhanced multiphoton ionization (REMPI) is used to generate volume ionization within an air-fuel flow and induce an ignition arc. The output of a relatively low energy single pulsed ultraviolet laser is aimed across an electric field inside a volume of air to create a pre-ionized channel so that a smaller voltage electric field is sufficient to create an electrical arc that follows the pre-ionized channel and will ignite an air-fuel mixture. Because the arc follows the pre-ionized channel, it can be directed to an optimal location inside an ignition volume for igniting the air-fuel mixture. A specific example embodiment is described using a 287.5 nm wavelength pulsed ultraviolet laser to excite ground state oxygen molecules to a specific excited state having a coincident term energy with a specific nitrogen molecule excited state.
