Solar-thermal hybrid power plant for use in sea water desalination plant, has controllable sewage sludge firing equipment arranged downstream for overheating of water vapor at day time and for steam generation at night

摘要

The plant (1) has a steam-/water circuit (3) and turbine units (5, 6) with a generator (7). A controllable sewage sludge firing equipment (13) is arranged downstream for overheating of water vapor at day and steam generation at night, where condensation heat from the turbine stage is used for drying sewage sludge (15) and preparing drinking water in a sea water desalination plant (19). Electric current and clean drinking water are produced and sewage sludge is cleaned during day and night, independent of presence of the sun, where sea water (22) is used for reducing residual waste heat.
