摘要

APPARATUS FOR HEATING A CONTAMINATED FEEDWATER FOR STEAM FLOODING An apparatus for heating a fluid in which a vapor generator is provided which includes a furnace section for combusting a fuel and means to pass water in a heat exchange relation to the furnace section to convert the water to steam. A heat exchanger is provided in fluid flow communication with the furnace section for receiving the steam and for passing the steam in a heat exchange relation with the fluid to preheat the fluid. An additional heat exchanger is provided adjacent the furnace section for receiving the combustion gases from the furnace section and passing same in a heat exchange relation with the preheated fluid to apply additional heat to the fluid.
