Abstract

The invention relates to a solar thermal steam generator (5) comprising a container (15) provided with an inlet (13) and an outlet (14) for guiding a heat transfer medium, also comprising heat exchanger tubes (18) which are arranged in the container (15) and through which a working medium flows, said tubes being configured so that heat from the heat transfer medium can be transferred to the working medium. Said heat exchange tubes (18) comprise at least part of the ribs (21) on their innner side.
