Ce procédé consiste à augmenter la température de la chambre chaude (10) possédant un ajutage de combustion (16) à une température égale ou supérieure au point d'ébullition du kérosène au moyen d'une unité de réchauffement (12), à introduire du kérosène et de l'eau séparément dans la chambre chaude réchauffée (10) par l'intermédiaire de conduits respectifs (26, 28) et à insuffler de l'air dans la chambre chaude (10) au moyen d'une soufflerie (34), le kérosène et l'eau vaporisés par la chaleur depuis la chambre chaude (10), ainsi que de l'air, étant évacués par une pluralité d'orifices (16K) de l'ajutage (16) et mis à feu par un transformateur de courant haute tension (18) et par une électrode d'allumage (20).
