MODIFICATION OF COMBUSTION REACTION DYNAMICS

摘要

The combustion reaction dynamics in a gas turbine combustion chamber (11) are modulated to improve combustion stability and/or reduce or nullify troublesome vibrations by using a gas flow restrictor (20) which has one or more restrictor holes (21) and is positioned in a gas passage (16) upstream of a gas injector orifice (17) and preferably closely spaced thereto.
