METHOD AND DEVICE FOR PREVENTING DRY-OUT IN A BOILER OF A TOWER SOLAR CONCENTRATION POWER PLANT

摘要

A method for generating a steam cycle at a pressure around 200 bars and a temperature around 600° C., using an industrial steam generator with a solar receiver admitting an incident solar flux around 600 kW/m², includes: generating a water-steam mixture in the evaporator by transferring heat from the incident solar flux onto the evaporator; separating the water-steam mixture into saturated water and saturated steam in the separator drum, the saturated steam having a pressure from 160 to 200 bars and a temperature from 347 to 366° C.; injecting the teed water into the mixing drum, where it is mixed. with the saturated water from the separator drum, the mixed water next returning toward the evaporator via the return pipe provided with the circulation pump, such that the temperature of the mixed water entering the evaporator is below the saturated steam temperature, by a value from 5 to 15° C.
