Abstract
A high output, high pressure direct contact steam generator for producing high quality steam particularly suited for use with low grade, low cost fuel. When used in a system incorporating heat recovery and conversion of carryover water enthalpy into shaft horesepower, the unit disclosed provides high quality, high pressure steam for 'steam drive' or thermal stimulation of petroleum wells through injection of high pressure steam and combustion gas mixtures. A particular feature of the burner/system disclosed provides compression of a burner oxidant such as atmospheric air, and shaft horesepower for pumping high pressure feedwater, from a lowest cost energy source such as leased crude, or other locally available fuel.
