Abstract: The invention concerns a gas turbine system, comprising a compressor, at least one combustion chamber (10), and eventually a secondary combustion chamber, for generating working gas. An intermediate turbine may be placed between two combustion chambers.
The combustion chamber (15) consists of an individual can-combustor (120) or a number of can-combustors (120) arranged in an annular can-architecture. The can-combustor (120) comprises a number of premixed burners (10) arranged uniformly or divided at least in two groups. One or more groups of the premixed burners (10) may be shifted along the combustor axis with respect to another group, and may also be inclined with respect to the combustor axis.
Optional Helmholtz dampers (16) reduce combustion pulsations.
Ignition of the mixture starts at the premixed burner outlet. The flame is stabilized in the region of the premixed burner outlet by means of a backflow zone.

Abstract: The present invention is related to methods and systems for preventing the release of nitrogen oxides with combustion flue gases emitted to the atmosphere. The invention is specifically directed to the removal of nitric oxide, nitrogen dioxide, and nitrous oxide from flue gas in stationary combustion systems. The methods of the invention improve efficiency of conventional reburning and advanced reburning processes by two key improvements, including the injection of a reducing agent into the reburning zone (16) and the use of promoters, which considerably enhance NOx control. The promoters are metal-containing compounds that can be added to the reducing agents. These improvements allow either one or two stages of reducing agent injection for greater NOx control (50).

Abstract: Processes and systems for producing glass fibers having regions devoid of glass using submerged combustion melters, including feeding a vitrifiable feed material into a feed inlet of a melting zone of a melter vessel, and heating the vitrifiable material with at least one burner directing combustion products of an oxidant and a first fuel into the melting zone under a level of the molten material in the zone. One or more of the burners is configured to impart heat and turbulence to the molten material, producing a turbulent molten material comprising a plurality of bubbles suspended in the molten material, the bubbles comprising at least some of the combustion products, and optionally other gas species introduced by the burners. The molten material and bubbles are drawn through a bushing fluidly connected to a forehearth to produce a glass fiber comprising a plurality of interior regions substantially devoid of glass.
