Patent ID: 6941756

Claim:
A fluid heating device for heating fluid material powered by fluid flow of said fluid material comprises; a heat exchanger chamber having pairs of transversely spaced parallel aligned interconnected bores within having a fluid inlet and a fluid outlet, at least one turbine drive assembly positioned outside of said heat exchanger chamber, a drive shaft extending from said remote turbine drive assembly through said heat exchanger chamber, means for directing a fluid flow first through said turbine drive assembly independent of said heat exchanger chamber and then through said interconnected bores within same heat exchanger chamber, a plurality of disks secured to said drive shaft outside of said heat exchanger being rotated thereby, one of said disk frictionally engaged on an outside surface of said heat exchanger chamber affording a thermal transfer thereto, means for resiliently urging said disks against said outside portion of said heat exchanger chamber, said fluid flow circulating through said heat exchanger chamber becomes heated due to the friction against a portion of said heat exchanger chamber by said disk, said heated fluid flow being isolated from said turbine drive assembly.
