Abstract: The present invention relates to a method of cleansing waste gases from their nitrogen oxide (NOx), hydrocarbon (HC) and carbon monoxide (CO) contents, such as the waste gases or exhaust gases originating from burners and internal combustion engines, wherein the waste gases, or exhaust gases are led through a catalyst for catalytic cleansing of the gases. The invention is characterised by bringing the lambda value (L) to a level beneath L = 1; leading the gases through a first catalyst (8) and then through a second catalyst (9); bringing the CO-content of the gas in the first catalyst (8) to a sufficiently high level to reduce NOx to N2 to an extent such as to bring said NOx content to a predetermined level; and delivering sufficient oxygen (O2) between the first and the second catalysts (8, 9) to oxidise both CO and HC to CO2 and H2O to an extent such as to reduce the CO-content of the gas to a predetermined level. The invention also relates to a gas burner.

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: A method of cleansing nitrogen oxide (NOx), hydrocarbon (HC) and carbon monoxide (CO) from waste gases, such as the waste gases or exhaust gases originating from burners and internal combustion engines. The waste gases, or exhaust gases, are passed through a catalyst for catalytic cleansing of the gases. The air-fuel ratio, or the lambda value (L), is reduced to a level below L=1. The gases are passed through a first catalyst and then through a second catalyst, to bring the CO-content of the gas in the first catalyst to a sufficiently high level and to reduce NOx to N2 to an extent such as to bring the NOx content down to a predetermined level. Sufficient oxygen (O2) is delivered to the gases at a point between the first and second catalysts to oxidize both CO and HC to CO2 and H2O to such an extent as to reduce the CO-content of the gas to a predetermined level. A gas burner to carry out the method is also disclosed.
