Solar thermal plant, has absorption pipe with parabolic trough concentrators to collect solar radiation which heats compressed air, where air upon heating expands in piston engine and plant components are designed as per thermodynamic laws

摘要

The plant has a reciprocating piston compressor to compress atmospheric air at high pressure, and an absorption pipe (2) with parabolic trough concentrators to collect the solar radiation. The compressed air is heated by the radiation and expands in a piston engine. A portion of the mechanical energy of the engine is used for driving the compressor via a positive coupling. The plant components are designed as per the thermodynamic laws.
