    摘要： A lightweight highly efficient vapor generator having low thermal inertia and fast response to varying load demands, particularly for automotive use. A series of radially spaced concentric heat sleeves surrounds the combustion chambers with incoming air passing between these sleeves for preheating the air used for combustion, this air providing heat insulation for the outer shell. An air register at one end of the shell imparts a swirling circular motion to the incoming air creating a vortex flow in the primary combustion chamber which continues on into secondary and tertiary combustion chambers. The wall of the tertiary combustion chamber is lined with vapor superheat tubes which receive vapor from banks of vapor generating tubes near mid length position in the shell, and these tubes in turn receive liquid from preheater tubes at the opposite end of the shell. The combustion gases pass between these tubes and exhaust from said opposite end of the shell. All radiant energy from the combustion chambers is intercepted and utilized with a minimum of loss to the outer shell.
