A gas generator is provided for generating gas including steam and carbon dioxide from the combustion of a hydrocarbon gas with oxygen. The gas generator includes an enclosure with an induction head (201) having an oxygen inlet and a fuel inlet therein, an adapter block (202) to which the induction head (201) attaches and a mixing chamber (203) to which the adapter block (202) is attached. The fuel and oxygen enter the enclosure by first passing through the induction head (201). A start up igniter (210) is located within the induction head (201) to ignite the fuel and oxygen mixture within the enclosure. The adapter block (202) includes a shroud extending away from the induction head (201) and which defines a combustion chamber within the enclosure. The fuel and oxygen mixture is combusted within the combustion chamber before passing out of the shroud of the adapter block (202) and into the mixing chamber (203). The mixing chamber (203) includes a water inlet for the induction of water into the mixing chamber (203) to cool the combustion products exiting the combustion chamber and heat the water entering the mixing chamber (203) from the water inlet. The gas generator generates gas both directly as steam and carbon dioxide which are products of the combustion of the hydrocarbon fuel and the oxygen and by raising a temperature of the water entering the mixing chamber (203) from the water inlet to above its boiling point such that the water is turned into steam. The steam from the combustion chamber and the steam from the water separately entering the mixing chamber (203) are mixed and discharged together at an end of the mixing chamber (203) opposite that of the adapter block (202). The oxygen entering the induction head (201) is free of nitrogen so that the products of combustion are free of nitrogen containing pollutants.
