evaporador de fuxo direto

摘要

A continuous evaporator for a horizontally constructed waste heat steam generator is provided. The continuous evaporator includes a first evaporator heating surface having a plurality of essentially vertically arranged first steam generator tubes through which a flow medium can flow from bottom to top, and a second evaporator heating surface which is mounted downstream of the first evaporator heating surface on the flow medium side. The second evaporator heating surface includes a plurality of additional essentially vertically arranged second steam generator tubes through which a flow medium can flow from bottom to top. The second steam generator tubes are designed in such a manner that the average mass flow density which can be controlled in the full load operation does not fall below a predetermined minimum mass flow density in the second steam generator tubes.
