'VITIATED STEAM GENERATOR' invention patent for a device which produces 'vitiated' steam i.e., it contains small amounts of combustion gases. It consists of a Combustion Chamber (2), a vaporizing chamber (10), a water atomizer and a water jacket (2) for cooling functions. Its purpose is the capability of producing steam instantly, in the desired amount, pressure and temperature. It has dimensions weight and cost greatly reduced. If compared to the conventional Boiler Concept, dispensing the pre-heating that occurs in the Boiler, and it dispenses the need of a superheater. It also dismisses the need of a reservoir to hold the produced steam. The Vitiated Steam Generator performs the same functions as the Boiler concept, with a much larger efficiency, as it doesn't produce heated gases, by-products of the burning fuel into the atmosphere. This process is applicable wherever there is a need for steam, where a small contamination of steam by combustion gases is bearable, like substituting boilers is producing vapour to power turbines in electric power plants, etc. It can also be used as an innovation in the injection of steam in oil wells for the recovery of mature wells 'on site' (i.e., with the generator being installed directly in the well).
