摘要：A gas generator for use in a borehole for generating steam and other hot gasesfor use in recovering hydrocarbons or other fluids from underground formations. Thegas generator comprises a housing forming a chamber with a combustion zone at oneend and a restricted outlet at the other end. A second zone is located downstream of thecombustion zone and a gas and water mixing zone is located between the second zoneand the restricted outlet. The generator has a cooling annulus surrounding the chamberwith passages leading from the annulus to the gas and water mixing zone. Methane isburned in the combustion zone with just enough oxygen to maintain the flame
temperature below the decomposition temperature of methane to convert substantiallyall of the carbon to carbon monoxide and to form hydrogen. In the second zone, thecarbon monoxide and hydrogen are burned with an additional supply of oxygen toincrease the temperature and to form carbon dioxide and hydrogen. Water is supplied tothe annulus for cooling purposes and for injection into the gas and water mixing zone forcooling the gases therein and for forming steam whereby hydrogen, steam, and carbondioxide are injected from the restricted outlet.
