Abstract:
An operating method for a solar collector plant, said solar collector plant comprising a radiation absorber (1) having a surface layer facing the sun and a downward running channel system just underneath said surface layer for conducting a liquid (12) removing heat from said surface layer, particles (11) inside the channel system for lifting said liquid (12) by capillary effect for sweeping the under side of said surface layer, and a pump (7) providing circulation of said liquid (12) through said absorber (1), a pipe system (2, 3, 4, 5), and a heat storage system (6) of the solar collector plant and operating in a start-up phase and a continuous operation phase, the operating method comprising:driving said pump (7) intermittently in the start-up phase with a number of shut-down periods and subsequent restarts, and controlling said pump by a control unit (13), for achieving effective removal of air from the absorber channel system.
