Title
(EN) SYSTEM FOR VAPORIZATION OF LIQUID FUELS FOR COMBUSTION AND METHOD OF USE
(FR) SYSTEME DE VAPORISATION DE COMBUSTIBLES LIQUIDES POUR LA COMBUSTION ET PROCEDE D'UTILISATION
Abstract
(EN)
A gas stream with a reduced oxygen concentration relative to ambient air is used to vaporize a liquid fuel or liquified hydrocarbon gas, or is mixed with a vaporized gas, and the reduced oxygen vaporized fuel gas is fed to a combustion device such as a premixed or diffusion combustor. Preferably, the oxygen content of the gas stream is less than the limited oxygen index. By mixing the fuel with a gas stream that has an appropriately reduced oxygen content, auto-ignition prior to the flame front can be avoided. In some embodiements, the reduced oxygen stream is generated from an air separator or taken from the exhaust of the combustion device.
(FR)
Un courant gazeux à concentration en oxygène réduite par rapport à l'air ambiant est utilisé pour vaporiser un combustible liquide ou un gaz d'hydrocarbure liquéfié ou est mélangé à un gaz vaporisé, le gaz combustible vaporisé à teneur en oxygène réduite étant envoyé dans un dispositif de combustion tel qu'une chambre de combustion à prémélange ou à diffusion. De préférence, la teneur en oxygène du courant gazeux est inférieure à l'indice limite d'oxygène. En mélangeant le combustible au courant gazeux à une teneur en oxygène réduite de façon appropriée, on peut éviter l'inflammation spontanée avant le front de flamme. Selon certains modes de mise en oeuvre, le courant à teneur en oxygène réduite est généré depuis un séparateur d'air ou évacué d'un dispositif de combustion.
