Abstract
The invention discloses a flow distribution-uniform compact steam generator. The flow distribution-uniform compact steam generator comprises a heat exchange unit, an inlet header, an outlet header, a shell side guide part and a shell assembly. A turbulent swirl decomposition part is arranged in a pressure cavity of the heat exchange unit for breaking large swirls caused by water feeding turbulent currents in the cavity; and under the precondition of guaranteeing uniform flow distribution of water in the cavity fed in a heat transfer pipe, the space size needed by the pressure cavity can be reduced. According to the size and working medium parameter requirements of the steam generator, the heat exchange unit can flexibly adopt a parallel or series connecting mode; and each heat exchange unit can be independently isolated, so that the operability of the steam generator is improved, and the afterheat discharge function is satisfied.
