Abstract: There is provided a continuous combustion system for iron particles. The system comprising a multi-annular combustion tube defining in cross-section at least three distinct passages from its inlet to its outlet. A first tube that is innermost, defines a first passage providing a primary air flow with suspended iron particles. A second tube, defines an inner annular space providing a secondary air flow, a pilot combustible flow, and an ignition point of a spark generator. A third tube defines a third passage comprises a swirl generator and provides a tertiary air flow. The tubes are nested in position within the multi-annular combustion tube. The system comprises a divergent nozzle at the outlet of the multi-annular combustion tube: a combustion reactor in fluid communication with the divergent nozzle, for the generation and stabilization of a turbulent iron flame that burns the iron particles and produces oxidized iron particles; and a cyclone.

Abstract: A method and structure for operating a combustion system of a gas turbine engine to mitigate low frequency combustion acoustics is generally provided. The method includes flowing an oxidizer through a fuel nozzle passage defining an inner wall and an outer wall, in which each of the inner wall and the outer wall are contoured from a first radius to a second radius smaller than the first radius; flowing the oxidizer at a higher axial velocity at the inner wall relative to the outer wall upstream of a fuel injection port; flowing a fuel through the fuel injection port to the fuel nozzle passage to mix with the flow of oxidizer to produce a fuel-oxidizer mixture; and igniting the fuel-oxidizer mixture downstream of the fuel injection port.

Abstract: An injection system for a turbine engine combustion chamber is provided. The injection system includes a first annular deflector surrounded by the bowl of the injection system and extending in the downstream direction from the downstream transverse surface that delimits the downstream side of the swirler. The first deflector has a free downstream end offset in the upstream direction from a downstream end of the bowl, so as to guide an air film output from the first orifices formed through the bowl. The internal radius of the cross section of the first annular deflector increases from the downstream transverse surface as far as the downstream end of the first annular deflector.

Abstract: This is an upright heater igniting combustible gas to induce a naturally aspirated flame within a glass tube. Air channels producing the naturally aspirated flame enters the glass tube in a direction perpendicular to the direction of the flame thus creating a twirling flame. Heat waves generated by the twirling flame within a glass tube rises to a heat concentrator and projected onto a parabolic heat shield thus reflecting the heat wave radially downward and outward.
