ABSTRACT:
The movable combustion system includes an outer liner defining a venturi and a centerbody including an inner liner terminating in swirler blades defining a gap at the rearmost end of the centerbody with the venturi. A secondary fuel nozzle lies within the centerbody. The centerbody is mounted to the combustor cover for axial translational non-rotational movement from a location outside the cover and during gas turbine operation to axially displace the secondary fuel nozzle and alter the gap between the centerbody and the venturi.
