Abstract: Systems and methods generate steam mixed with desired non-condensable gas concentrations using a direct steam generator. Injecting the steam into a reservoir may facilitate recovering hydrocarbons from the reservoir. Cooling an output of the direct steam generator produces water condensate, which is then separated from the non-condensable gas, such as carbon dioxide. Reducing pressure of the condensate subsequently heated by cross-exchange with effluent of the direct steam generator regenerates the steam with the carbon dioxide removed for the injection.

Abstract: Systems and methods utilize heated waste flue gas to treat water. The heated waste flue gas, which may come from a steam generator, bubbles through untreated water to vaporize the untreated water and separate out solids and other contaminants before subsequent condensing. The steam generator may receive resulting treated water to produce steam for injection.

Abstract: Systems and methods utilize heated waste flue gas to indirectly heat untreated water. The heated waste flue gas, which may come from a steam generator, passes through one or more heating coils in a vessel to vaporize untreated water and separate out solids and other contaminants before subsequent condensing. The steam generator may receive resulting treated water to produce steam for injection.

Abstract: The invention comprises a motor driven machine, the machine such as a lathe, drill, router, saw, or shaping tool includes a machine spindle and a switch reluctance motor having a motor spindle. The construction is such that the longitudinal axis of the motor spindle and the longitudinal axis of the machine spindle lie on substantially the same axis. In one form of the invention the machine spindle and motor spindle can be unitary.
