STEAM GENERATING GEAR Russian patent published in 1999 - IPC

FIELD: production of steam in power plants, phase separation of mixtures. SUBSTANCE: heated working fluid which vortex-type flow boils while passing to center of compartment is pressure-fed into inlet compartment 4 of cylindrical body 1 through tangential branch pipe 8. Bubbles of steam collect in central part of body and steam is supplied over central pipe 10 to user. Working fluid goes from inlet compartment 4 into outlet compartment 5 through central hole 3 in lateral partition 2, moves rotating from axis to periphery of compartment and carried away through diffuser branch pipe 9 from central body 1. Compartments 4 and 5 have form of contraction transforming into diffuser 7 along flow of working fluid. EFFECT: decreased power needed to pump through working fluid flowing through steam generating gear. 4 cl, 3 dwg
