CAVITATION HEAT GENERATOR Russian patent published in 1999 - IPC

FIELD: heating equipment, in particular, for heating viscous liquids, like petroleum directly in pipe lines, for example, for heating civil premises and fuel supply of power-consuming industries. SUBSTANCE: accelerator of liquid movement is designed as flow chamber with supply pipe, converging tube and exhaust pipe for processed liquid. Flow chamber contains super-cavitation blades which are mounted on boss. External surface of these blades is embraced by coaxial cylinder which external surface carries another group of super-cavitation blades with opposite direction of flow vortex. Inner group of super- cavitation blades is mounted on boss. Braking unit is designed as flow interruption unit with drive which is located behind working member along direction of flow. Exhaust pipe is connected to heat accumulator which is connected to heat consumers and trunk pump, which output is connected to supply pipe through housing. EFFECT: increased rate of liquid heating, increased efficiency of device operations. 11 cl, 3 dwg
