In a fuel and oxidant combustion system, a flame holder support structure includes a heating element that receives electrical energy from an electrical power source. The heating element is raised to an auto-ignition temperature of a fuel and oxidant mixture directed, along an axis proximate the flame holder support structure, to a flame holder for combustion thereof.

A combustion system includes an electrically actuated flame location control mechanism.

A combustion system includes an electrically actuated flame location control mechanism.

A dynamic pressure exchanger configured for a combustion process includes an inlet plate and a rotor assembly mounted for rotation relative to the inlet plate about a central axis of the dynamic pressure exchanger. The inlet plate is formed to include an inlet port configured to direct air into the rotor assembly. The rotor assembly includes an inner rotor and an outer rotor arranged around the inner rotor.
