H.R.S.G. (Heat Recovery Steam Generator) - Zhen Hai (CHINA): November 2004 - May 2005

Collaboration for the supply of calculations and checks of two Heat Recovery Steam Generators (H.R.S.G.) to be erected at the ZhenHai power plant (China). The HRSG consists of a box shaped steel superstructure with dimensions in plan of 11,8x24,5m and height above ground of approximately 26,0m. The casing panels are formed by 6mm to 10mm thick steel plate strengthened by welded stiffeners. The steel superstructure is made by 6 transversal frames connected by longitudinal roof girders. The stability against the horizontal loads (wind and seismic actions) is provided by portal frames in the transversal direction and by casing plates in the lognitudinal one.
The load analysis and checks have been carried out according to the following codes:
  • AISC-ASD 9th edition;

  • UBC '97 - Vol. 2, Chp 16;

  • BS 5950: Part 1: 1990.
