FIELD: heat engineering. SUBSTANCE: jet plant has jet apparatus with intake branch pipe, intake chamber, mixing chamber and nozzle. Plant is fitted with overflow pipe-line and throttle. Intake branch pipe is linked on side of its inlet to confuser section of overflow pipe-line. Mixing chamber communicates with diffuser section of overflow pipe-line. Throttle is positioned in overflow pipe-line. Axis of mixing chamber makes acute angle with axis of overflow pipe-line. Cool heat transfer agent is accelerated and part of it is carried into jet apparatus. The other part is throttled with formation of zone of reduced pressure along wall of diffuser conduit. Steam is fed into nozzle of jet apparatus in the capacity of hot heat transfer agent. Two-phase flow with its transformation to supersonic flow is formed downstream from nozzle with mixing of heat transfer agents. It is decelerated with transformation of two-phase flow in pressure jump to single-phase fluid flow. This flow is supplied to zone of reduced pressure and its boiling is organized in it with formation of two-phase supersonic flow which is decelerated with transformation to fluid flow of heat transfer agent in process of mixing with cool heat transfer agent. EFFECT: enhanced operational reliability of plant. 6 cl, 1 dwg |
