Abstract
Abstract An apparatus for vaporizing a multicomponent liquid consists of a vaporization chamber into which liquid is injected through a nozzle with sufficient velocity to ensure multiple impingements with the heated surfaces of the chamber so that vaporization is substantially complete. The apparatus may have a plurality of injection nozzles, each responsive to a valve. The valves are sequentially operated by a control circuit to provide a substantially continuous stream of liquid to the vaporization chamber.
