Title (EN) DUAL PHASE FUEL VAPORIZING COMBUSTOR
(FR) CHAMBRE DE VAPORISATION A COMBUSTION DE CARBURANT, A DOUBLE PHASE
Abstract:
(EN) A method for burning high viscosity, high carbon/hydrogen ration hydrocarbon fuels in a vaporizing combustor. A dual phase vaporizer tube (40) receives alternately a fuel air mixture of high fuel content, and then a hot air or low fuel content mixture. A vapor stream of combined air and partially vaporized fuel from the tube is impinged on a hot surface (88, 90) where the more volatile portions of fuel will vaporize and bum, while the less volatile heavier fuel components will form a hot carbon deposit on the surface and alternately thereafter a hot, highly oxidizing stream with little or no fuel is discharged from the tube and impinged onto the carbon deposit on the hot surface and thereby promote substantial burning of the carbon. These operations are alternately and sequentially performed.
(FR) Methode pour bruler des hydrocarbures a grande viscosite et forte teneur en carbone/hydrogene dans une chambre de vaporisation a combustion. Un tube vaporisateur a double phase (40) recoit alternativement un melange carburant/air riche en carburant, puis de l"air chaud ou un melange pauvre en carburant. Un courant de vapeur combine d"air et de carburant partiellement vaporise provenant du tube est projete contre une surface chaude (88, 90) ou les parties les plus volatiles de carburant se vaporisent et brulent, tandis que les parties de carburant plus lourdes et moins volatiles forment un depot chaud de carbone sur la surface puis, successivement, un courant chaud hautement oxydant decharge par le tube est projete le depot de carbone de la surface chaude, activant ainsi substantiellement la combustion du carbone. Ces operations ont lieu alternativement et successivement.
