Kanjanaburi Solar Thermal Power Plant with Direct Steam Generation – Layout

A solar thermal power plant with parabolic trough collectors is being erected in Kanchanaburi, Thailand. It will supply electricity to the public grid for which a feed-in tariff is foreseen. For the first time direct steam generation will be applied in a commercial plant consisting of an evaporator and a superheater field. It combines the recirculation concept and injection cooling. Also the solar collectors are constructed with an innovative approach. They are made out of fibre glass/resin enclosing foam and are reinforced with a space frame taking torsion forces. The paper focuses on the layout of the solar thermal power plant
