Plasma assisted combustion for the reduction of NOx from land-based turbines. A collaboration with Rolls-Royce Canada and McGill University.
Plasma can affect the combustion process as well as the ignition of hydrocarbons in two ways. The first is the thermal effect that includes Joule heating and convective mixing. The second is the non-thermal effect that includes ion/electron drift as well as excitation, ionization, and dissociation of molecules.
We are primarily interested in the effects of streamers from a high-voltage nanosecond pulsed discharge for the reduction of NOx emissions at atmospheric pressure in land-based turbines. The high value of the electric field at the head of these streamers provides adequate conditions for the sustained production of radicals affecting the combustion process.
Previous experiments carried out with a 10 kV rms , 10 kHz, AC power supply have demonstrated the adverse effects of a thermal arc for the production of NOx all the while demonstrating improved flame stability and lean combustion enhancement.
This master’s project includes the development and characterization of such a discharge. Time-resolved optical emission spectroscopy will be used to relatively quantify the production of radicals as well as provide insight on their decay through collisional recombination. The energetic contribution provided by the discharge will be quantified by the electrical characterization of the power supply assembly.
