Abstract
An inline heating device for fluid has rotary members frictionally engaging fixed housing extensions on a central fluid transfer conduit. The rotary members are rotated by drive shafts having multiple vein turbine assemblies respectively thereon within the fluid transfer conduit. The rotary members have enhanced friction engagement surface which are spring urged against the fixed housing extension engagement surfaces generating heat therein for thermal transfer to the fluid flow within the transfer conduit driving the turbine assemblies.
Claims12
A heating device for heating fluid material powered by said fluid material comprises;
- a cylindrical support housing having a fluid inlet and a fluid outlet,
- at least one turbine assembly within said cylindrical support housing, a drive shaft means extending from said turbine assembly,
- means for diverting fluid flow within said cylindrical support housing for engagement with said turbine assembly,
- a plurality of disks secured to said drive shaft being rotated thereby, a thermal transfer housing extending from and in communication with said cylindrical support housing, a portion of said thermal transfer housing frictionally engaged with said respective disks,
- means for resiliently urging said disks against said portion of said thermal transfer housing,
- means for supporting and enclosing said disks extending from said thermal transfer housing,
- means for pressure relief within said disk enclosing means,
- said fluid flow circulating through said cylinder support housing and said thermal transfer housing driving said turbines whereby said fluid becomes heated due to the friction against a portion of said thermal transfer housing,
- said heated thermal transfer housing transferring heat to said fluid flow there within.
