Working Group 3: Technical Expert Group on Cooling and Solar Updraft Towers

Mission

1. To initiate research activities in the fields of efficiency, reliability and durability of steel and concrete cooling towers and comparable structures, such as:
  • natural draught cooling towers in wet-cooling-systems
  • natural draught cooling towers in dry-cooling-systems
  • fan-assisted cooling towers
  • hybrid cooling Towers
  • updraft towers of solar thermal power plants

2. To gather cooling tower experts from universities, power plant operators, cooling technologies companies, building companies and engineering consultancies from all over the world.
3. To improve the standards and recommendations for cooling tower design, construction, quality management, maintenance, repair and strengthening.
4. To organize international symposia and sessions on cooling towers and solar chimneys as “state-of-the-art”-events.

Background

Much of the recent activity of WG 3 has related to VGB PowerTech e.V., abbreviated VGB, the European technical association for electricity and heat generation.  VGB is divided into Competence Centers for

  • Nuclear Power Plants
  • Fossil-fired Power Plants
  • Renewables and Distributed Generation
  • Environmental Technology, Chemistry, Safety and Health
  • Operational Services

VGB is an association of companies, who focus on power plant operation and related technologies. Currently in total 462 members, comprising operators, manufacturers and institutions connected with energy engineering, are organized in VGB.  They come from 33 countries worldwide and represent an installed power plant capacity of 520,000 MW, 461,000MW of which are in Europe.  The tasks are to utilize international experience and bundle it in VGB Standards and Guidelines, for example for the Structural Design of Cooling Towers.  The offices of VGB PowerTech are located in Essen/Germany.

Current Objectives

  1. To extend WG3 to a larger group of engineers, especially outside of Europe.
  2. To evaluate new editions of cooling tower guidelines within VGB PowerTech Association.
  3. To co-operate with the International Association for Industrial Chimneys CICIND in the design and construction of chimneys and cooling towers made of reinforced concrete.
