Steam generator for solar thermal power plant, has several air duct arranged evaporator tubes which are traversed by flow medium that is partially vaporized by heat transfer medium at several points of evaporator tubes

摘要

The steam generator has a wall (82) that is formed in air duct for guiding heated air as heat transfer medium (G) and several air duct arranged evaporator tubes (81) which are traversed by flow medium (M) that is partially vaporized by heat transfer medium at several points of evaporator tubes. The evaporator tubes are connected with pressure compensating unit (83).
