Abstract

A steam generator for converting a fluid to steam includes a combustion chamber for receiving a combustion fuel into the combustion chamber. A steam chamber surrounds and is heated by the combustion chamber to a temperature exceeding a vaporization temperature of the fluid. A heat exchanging chamber surrounds and is heated by residual heat of the steam chamber. A preheating coil is disposed within the heat exchanging chamber and has a fluid inlet for receiving the fluid under pressure into the preheating coil for preheating the fluid within the heat exchanging chamber. An injector communicates with the preheating coil and the steam chamber for injecting a controlled flow of the preheated fluid under pressure into the steam chamber where it flashes to steam and is super-heated to the temperature of the steam chamber. A steam outlet conveys the super-heated steam externally of the steam generator.
