Layout of heating units for solar-heated gas turbine systems with paraboloid collectors. Die Auslegung von Erhitzern Solar beheizter Gasturbinenanlagen mit Paraboloidkollektoren

Abstract

Solar energy is converted in a gas turbine plant, with solar radiation collected in a parabolic collector and reflected into a hollow receiver. The receiver, which is rigidly connected to the collector, consists of a conical bottom part and a cylindrical upper part. The highly focussed radiation enters through the aperture of the conus. The cool, compressed working fluid of the gas turbine flows through pipes arranged in front of the cylindrical inner wall. The distribution of the radiation was studied as well as the resulting receiver wall temperature, radiation losses and useful heat absorbed by the working fluid. Temperature distributions and three-dimensional fields of thermal stresses were calculated. The influence of geometric and thermodynamic parameters on the stresses inside the pipes was studied in consideration of thermal stresses and stresses due to working fluid pressure. The findings will help to optimize the heating surface load, material utilisation, and efficiency of the receiver. The interdependences between receiver characteristics and gas turbine operation are explained.
