Abstract
An apparatus, system, and method for controlling combustion gas output in direct steam generation for oil recovery. A direct combustion steam generator burns a fuel and an oxygen-containing gas mixture to produce combustion products including steam, COand N. Supplemental oxygen is separately supplied to the combustion steam generator to adjust the oxygen content of the oxygen-containing gas mixture during the combustion process in order to adjust the ratio of COto Nproduced in the combustion products.
