ABSTRACT:
A poppet valve system for controlling the air distribution within the combustor of a gas turbine. The cylindrical combustor includes a concentric combustion lining where air and fuel are mixed and burned near a flame holder, and a dilution air manifold that injects dilution air into the combustion lining downstream of the flame holder. Air enters the dilution air manifold and the liner mixing zone through openings that can be closed by poppet valves. Each poppet valve is operated to close either an opening in the combustion liner to the mixing zone or a corresponding opening in the dilution air manifold. The volume of air mixing with fuel in the mixing zone is controlled by operation of the poppet valves.
