An improved portable, versatile, modular, above-ground system and process for generating combustion gases, principally nitrogen and carbon dioxide, and steam, for removing particulate matter and corrosive components from the combustion gases, and for injecting the purified nitrogen and CO2, and steam, individually or in selected mixtures, at controlled temperatures and pressures into a subterranean formation bearing hydrocarbons to enhance the recovery thereof. The system includes a high-pressure combustion reactor for efficient generation of combustion gases at the required rates and at pressures up to about 8000 psi and temperatures up to about 4500°F. The reactor is water-jacketed but lined with refractory material to minimize soot formation. Combustion chamber temperature is reduced to a safe level by water injection with the fuel.

Apparatus for generating combustion gases at high pressures and high temperatures and steam for selective injection into subterranean formations to enhance recovery of hydrocarbons and other fluids therefrom, comprising: means defining a pressure-tight elongated combustion reactor having a restricted outlet at one end thereof for the discharge of combustion gases under high pressure; refractory material lining the wall of said reactor substantially throughout the interior thereof; burner means at the other end of said reactor for the supply of fuel and air thereto under high pressure to generate combustion gases in said reactor at high pressures and high temperatures; means for introducing water into the combustion flame in an amount sufficient only for reducing the temperature of the flame to a level non-destructive of said refractory material; means defining a steam boiler detachably connectable to said reactor outlet for the passage therethrough of, and the heating thereof by, the combustion gases created in said reactor to generate steam; and means for selectively injecting such steam into the formation with or alternatively to the gases.
