FIELD: heating engineering.
SUBSTANCE: heat-generator belongs to devices for producing heat without using fuel. Heat-generator has cylindrical stator and cylinder-shaped rotor inserted into stator. Cylinder has many radial recesses at its surface or in form of several discs. Any disc has at its cylindrical surface a number of recesses. It's offered to reduce depths of recesses gradually during moving from one end of rotor to the other at the direction of pass of fluid. It is also offered to insulate discs thermally one against another.
EFFECT: improved stability; higher efficiency of heating liquid up.
