HEAT-GENERATING UNIT FOR HEATING LIQUIDS Russian patent published in 2001 - IPC

FIELD: liquid heating appliances for heating buildings. SUBSTANCE: unit has cylindrical house with fuel-flow accelerating cyclone at its bottom, brake mechanism on its top, and outlet pipe connection joined to cyclone through transfer pipe; joint is made coaxially to cyclone on its butt end; the latter is tilted through 10 deg. to its radial section ; outer wall of injection nozzle at housing inlet is provided with guide vane attached to butt end of cyclone. Outer wall of injection nozzle and guide vane are built to constitute logarithmic spiral; length of guide vane is greater than πR/2, where R is inner radius of housing; cyclone and housing have equal radii. EFFECT: enhanced thermodynamic efficiency of energy conversion. 3 cl, 3 dwg
