A continuous flow stream of combustion products conducted through a chamber(18) is mixed with moisture-laden ambient air & ignited by discharge from a spark plug(40) connected to the high voltage terminal(42) of a secondary winding in an ignition coil assembly(44) having a primary winding connected between a source of DC voltage & a terminal exposed to a gaseous mixt. in the chamber. The high voltage applied to the spark plug is induced by intermittent interruption of the flow of current through the ionized gaseous mixt. grounded in the chamber resulting from restricted inflow of moistur-laden air into the chamber. |
