Abstract
A gas-turbine engine combustor having a plurality of venturi mixers, each includes an air inlet connecting to an air supply path, a fuel inlet connecting to a supply source of gaseous fuel, and an air-fuel mixture generating passage connecting to the air inlet and the fuel inlet and merges with an air-fuel mixture generating section to produce the air-fuel mixture and a nozzle opened into the combustion chamber at an end of the air-fuel mixture generating passage. In the combustor, the venturi mixers are arranged radially around a center axis of the combustion chamber, the air-fuel mixture generating passage is provided with a throttle section of diminishing diameter, and the nozzle is shifted circumferentially about the center axis relative to the air inlet such that the air-fuel mixture generating passage is deflected in a circumferential direction between the throttle sections and the nozzle, thereby expanding the premixed combustion range to realize further reducing of emissions, without producing backfire or self-ignition.
