Plasma injection modules

A plasma injection module, comprising:

• a fuel receiving end configured to receive a combustible material;
• a discharge end opposite the fuel receiving end;
• an axial fluid pathway extending between the fuel receiving end and the discharge end, an insulator assembly defining a first portion of the axial fluid pathway proximate to the fuel receiving end;
• a connection assembly positioned downstream of the insulator assembly and defines a second portion of the axial fluid pathway, wherein the connection assembly further comprises a compression ring, a compression seat, and a connection tube coupling the compression ring to the compression seat,
• an injection tube assembly positioned downstream of the insulator and the connection assembly, the injection tube assembly coupled to the insulator assembly via the connection assembly, the injection tube assembly including:
• an injection tube defining a third portion of the axial fluid pathway adjacent to the discharge end, the injection tube formed of an electrically conductive material;
• a permanent magnet arranged annularly about the injection tube proximate to the discharge end;
• and
• a nozzle surrounding the injection tube and the permanent magnet, the nozzle defining a fuel discharge opening proximate the discharge end;
• and
• a voltage input connection arranged downstream of the insulator assembly and the connection assembly and upstream of the injection tube assembly, the voltage input connection being configured to secure a voltage source to the injection tube to form a plasma filament within and adjacent to the axial fluid pathway,
• wherein during operation the permanent magnet produces a magnetic field that interacts with the plasma filament to rotate the plasma filament and increase an area of ignition between the plasma filament and the combustible material at the discharge end.

An ignition system comprising:

• a combustor having one or more fuel ports positioned on a flowside wall, and
• a plasma injection module coupled to the combustor, the plasma injection module comprising:
• a fuel receiving end configured to receive a combustible material;
• a discharge end opposite the fuel receiving end, the discharge end being positioned proximate the flowside wall;
• an axial fluid pathway extending between the fuel receiving end and the discharge end;
• an insulator assembly defining a first portion of the axial fluid pathway proximate to the fuel receiving end;
• an injection tube assembly positioned downstream of the insulator assembly, the injection tube assembly coupled to the insulator assembly, the injection tube assembly including:
• an injection tube defining a second portion of the axial fluid pathway adjacent to the discharge end, the injection tube formed of an electrically conductive material;
• a nozzle surrounding the injection tube, the nozzle defining a fuel discharge opening proximate the discharge end;
• a first insulating tube surrounding the injection tube;
• a second insulating tube surrounding the first insulating tube and a permanent magnet;
• and
• a containment cap or a tube surrounding the injection tube, the first and second insulating tubes, the permanent magnet, and the nozzle to secure the injection tube, the first and second insulating tubes, the permanent magnet, and the nozzle relative to each other;
• a voltage input connection arranged between the insulator assembly and the injection tube assembly;
• and
• a flow inducing device coupled to the injection tube proximate to the discharge end, wherein the flow inducing device is the permanent magnet arranged annularly about the injection tube.
