Abstract
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.
Claims8
An apparatus for heating a fluid comprising a vapor generator including a furnace section for combusting a fuel and means to pass water in a heat exchange relation to said furnace section to convert said water to steam;
- first heat exchange means disposed externally of said vapor generator in fluid flow communication with said furnace section for receiving said steam;
- said first heat exchange means including coil means through which said fluid is passed, said steam passing over said coil means to preheat said fluid;
- second heat exchange means disposed adjacent said furnace section for receiving the combustion gases from said furnace section;
- and means for passing said preheated fluid through said second heat exchange means to apply additional heat to said fluid.
