  • Patent number: 11781751
    Abstract: The present disclosure is directed to systems and methods for high flame temperature oxy-combustion that enables the capture of CO2 cost effectively. One part of the presently disclosed subject matter comprises an annular shroud burner which utilizes a supply of undiluted oxygen and minimal flue gas recycle to generate a high flame temperature to maximize efficiency. The annular shroud burner may deliver oxygen into a combustion zone where mixing of the oxygen and a stream of fuel occurs. Flue gas recycled from the exit of the combustion system serves the dual purpose of conveying the coal into the reaction zone, as well as providing local cooling and protection from high incident heat fluxes through the novel shroud cooling design. The annular shroud burner may be configured to produce an axial jet flame that controls the rate of mixing of oxygen and fuel, thereby extending the heat release. Oxygen and coal may be mixed in a ratio such that peak flame temperatures exceed 4,500° F. (2,482° C.

  • 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: 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: 9004909
    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: 20150079524
    Abstract: A low NOx burner includes a charging mechanism to charge a fuel stream or diluted fuel stream. A flame supported by the charged fuel stream can be held at a lifted location corresponding to high fuel dilution. If electrical power is lost or removed, the flame is shifted to a location corresponding to a lower fuel dilution.

  • Patent number: 8955467
    Abstract: A steam boiler includes a boiler housing. A helical coil for boiling water and superheating the wet steam is disposed within the boiler housing. A burner emits combustion gases which heat a heat emitter which is disposed in the inner space of the helical coil. Combustion gases from the burner enter the internal cavity of the heat emitter and then pass through perforations in the heat emitter before contacting the helical coil. As such, the heat emitter is heated by the combustion gases and serves as a radiant heat source for the helical coil.

  • Patent number: 8956154
    Abstract: Methods and systems for conversion of a carbon containing fuel to CO2 and H2O. An air stream is fed to a first ion transport membrane unit obtaining a pure oxygen stream from a permeate side and an air stream with a reduced oxygen content from a retentate side. The air stream with a reduced oxygen content is fed to a second ion transport membrane unit and a gaseous first carbon containing fuel is fed to a permeate side of the second ion transport membrane. The first carbon containing fuel is reacted with oxygen transported through the second ion transport membrane forming an at least partially combusted first fuel. The at least partially combusted first fuel, at least a part of the pure oxygen stream and optionally a second carbon containing fuel is fed to a combustion chamber for combustion. An exhaust stream comprising essentially CO2 and H2O is obtained.
