Stabilization of lean flames with nanosecond discharges in a gas turbine model combustor

Abstract

This work presents an experimental study of the stabilization of lean methane-air flames by nanosecond repetitively pulsed (NRP) discharges. The experimental facility consists of a gas turbine model combustor with a Lean Premixed Prevaporized multipoint injector. The fuel is injected through two stages, each stabilized by swirl. This facility is representative of a single sector of a gas turbine combustion chamber. The NRP discharges are found to significantly extend the lean blow-off limit for a wide range of operating conditions, with flame thermal powers up to 100 kW, and with an electric power less than 0.2% of the flame thermal power.
