Exhaust system combustor
Patent
·
OSTI ID:5135481
This patent describes a combustor for use in an exhaust gas system which combustor is tolerant to thermal gradients so as not to degrade the atomization of fuel therein. It comprises an exhaust duct for conveying exhaust gas therethrough having a side wall, an inlet end through which exhaust gas enters the exhaust duct, and an outlet end through which the exhaust gas exits the exhaust duct; a combustion chamber having an atomizer end and a combustion end fixedly mounted in the exhaust duct facing the outlet end of the exhaust duct; an atomizer mounted in the atomizer end of the combustion chamber for spraying atomized fuel into the combustion chamber; an air duct for conveying combustion air to the combustion chamber and extending through the side wall of the exhaust duct to the atomizer end of the combustion chamber; and a fuel conduit fixedly joined to the atomizer for conveying fuel to the atomizer, the fuel conduit having at least a portion thereof extending in the air duct, the portion also including a longitudinal compliance portion for allowing thermal expansion and contraction of the air duct and the combustion chamber relative to the fuel conduit while maintaining a constant position and alignment of the atomizer with respect to the combustion chamber.
