Abstract

An improved method and apparatus for heating fluids wherein separate gas streams of natural gas and air are compressed to a preselected pressure, passed to an injection and mixing zone for thorough mixing including expansion of one gas and compression of the other, passed to a combustion chamber for burning with the combustion products being further contracted and passed to a heat exchanger conduit where such combustion products are progressively further contracted as they are brought into heat exchange with the fluid to be heated.
