The present disclosure generally relates to the introduction of a liquid biomass in heating systems such as commercial boilers in order to reduce dependence on petroleum-based heating fuel oils as a source of combustion fuel. More specifically, the present disclosure is directed to systems, methods, and apparatuses utilizing a liquid thermally produced from biomass into commercial and industrial boiler or thermal systems such as boilers, furnaces, and kilns, and methods for generating renewable identification numbers (RINs), alternative energy credits (AECs) and renewable energy credits (RECs).

An acoustic damper for a rotary machine includes at least one wall, at least one inlet, at least one outlet, at least one separating wall, and at least one neck. The wall extends from the back side of a combustor front panel and defines a damping chamber. The inlet is defined within the wall and is oriented to channel a flow of air into the damping chamber. The outlet is defined within the back side of the front panel. The separating wall is oriented to separate the damping chamber into a first volume and a second volume. The first volume of the damping chamber is configured to damp an acoustic pressure oscillation at a first frequency. The second volume of the damping chamber is configured to damp the acoustic pressure oscillation at a second frequency. The neck extends through the separating wall and is axially offset from the outlet.

A combustor component of a combustor for combusting fuel to produce a combustion gas includes a combustion cylinder forming a passage for the combustion gas, a first acoustic device which internally includes a first cavity communicating with the passage via a first through hole formed in the combustion cylinder, a second acoustic device which is located on a radially outer side of the first acoustic device so as to cover the first acoustic device, and internally includes a second cavity communicating with the passage via a second through hole formed in the combustion cylinder, and a first communication passage causing the first cavity and an outer space of the combustion cylinder to communicate with each other without via the first through hole and the second cavity.

Disclosed is a combustion chamber (10) of the carbon dioxide supplier including: a combustion chamber (10) combusting a mixture of air and fuel; an air supply unit supplying an into the combustion chamber (10); and a fuel supply unit supply in a fuel to the combustion chamber (10). Representative Figure is FIG. 6.

A combustor may include a combustor shell, a particle collection panel, and a combustor panel. The combustor shell may define a plurality of first impingement holes, the particle collection panel may include a plurality of particle collection chambers and may define a plurality of second impingement holes, and the combustor panel may define a plurality of effusion holes. The particle collection panel may be disposed inward of the combustor shell and the combustor panel may be disposed inward of the particle collection panel. Each particle collection chamber may have a closed inward end and an opening defined in an outward end. The particle collection chambers may be configured to entrap particulates.

A gas turbine engine has a resonator ring that is formed by two circumferentially extending rings. The first and second circumferentially extending rings have located within them baffles. Both the first ring and the second ring are able to mitigate acoustic frequencies generated by the gas turbine engine.

Heat-exchange and noise-reduction panel for a propulsion assembly, in particular for an aircraft, the panel comprising: a perforated plate comprising a plurality of through-openings; a cellular structure comprising longitudinally oriented structural walls covered by said perforated plate and comprising, between said walls, cavities that define Helmholtz resonators, said through-openings forming necks of said resonators; and means for the circulation of fluid, for example oil, at said perforated plate, wherein said fluid circulation means comprise channels that are formed at least in part in thickened ends of said walls on the same side as said perforated plate, and/or at least in part in regions of the perforated plate situated in the longitudinal extension of said thickened ends.

Oxy-pyrohydrolysis articles, systems and methods for total halogen, in particular fluorine analysis are provided. A sample containing halogen elements is provided into a pyrotube for combustion. A combustion-enhancing bed including ceramic fibers or fabrics is disposed inside the pyrotube to enhance the combustion and protect the pyrotube from damage by corrosive gases.
