METHOD OF REGENERATIVE PREHEATING OF FEED WATER IN JET PREHEATER

摘要

FIELD: thermal power stations. SUBSTANCE: condensate and steam discharged from turbogenerator are accelerated, after which this steam and condensate are mixed forming two-phase mixture of condensate and steam and mixture is shifted to supersonic flow; then shock wave is organized in two- phase supersonic flow shifting two-phase flow in shock wave into single- phase subsonic flow of liquid at simultaneous heating of condensate due to condensation of steam and additional heating of condensate due to collapse of steam bubbles in shock wave. EFFECT: enhanced efficiency and reliability of jet apparatus. 3 cl, 2 dwge
