Gas and steam generator

Apparatus for generating high pressure fluid for a work operation and comprising at least first and second stage combustion chambers in open communication with one another, mixing valve means in communication with the first stage combustion chamber, passageway means in independent communications with a source of oxygen and a source of fuel for simultaneously directing the oxygen and fuel to the mixer valve for injecting a fuel-oxygen mixture into the first stage combustion chamber, ignition means in communication with the first stage combustion chamber for igniting the fuel-oxygen mixture therein, restriction port means interposed between the first and second stage combustion chambers to provide upstream pressure within the first stage combustion chamber in excess of the pressure released through the restriction port means into the second stage combustion chamber, inlet means open to the first stage combustion chamber in the proximity of the restrictive port means for admitting water bearing fluid into the downstream side of the first stage combustion chamber for mixing with the products of combustion of the ignited fuel-oxygen mixture as the products of combustion are released through the restrictive port means into the second stage combustion chamber, wherein steam is produced from the water bearing fluid and is heated to a super-heated stage, restrictive port means provided at the downstream end of the second stage combustion chamber for release of the super heated steam therefrom to provide useful energy.

Apparatus for generating high pressure fluid for a work operation and comprising a plurality of combustion chamber assemblies secured in end-to-end relation and having at least two interconnected combustion chambers provided therein, each of said combustion chambers being provided with a restrictive orifice at the outlet end thereof whereby high pressure and high temperature conditions are created in the upstream portion of the respective combustion chamber, mixer valve means provided in one of said combustion chamber assemblies and in open communication with the respective combustion chamber, first passageway means provided in the said one combustion chamber assembly in independent communication with an oxygen containing fluid and a fuel containing fluid for simultaneously directing the fluids to the mixer valve for discharge into the said respective combustion chamber, ignitor means provided in said one combustion chamber assembly and in operable communication with the said respective combustion chamber for igniting the fuel-oxygen mixture therein, second passageway means provided in said one combustion chamber assembly providing communication between the exterior thereof and the proximity of the restrictive orifice of said respective combustion chamber for simultaneously admitting water bearing fluid and a second fuel product into the products of combustion moving through the restrictive orifice of the said respective combustion chamber whereby the second fuel product and components of the water bearing fluid are ignited for burning and passed into the respective combustion chamber of the next succeeding combustion chamber assembly, the restrictive orifice of the last mentioned combustion chamber providing a discharge port for the high pressure fluids from the apparatus to provide energy for use in the work operation.
