ABSTRACT:
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 CO.sub.2, 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.degree. 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.
