Trianel Kohlekraftwerk Lünen GmbH & Co. KG owns a hard coal fired steam generator with an electrical output of 750 MW at the Lünen site. Due to severe corrosion on the inner walls of the steam generator, Dornier Power and Heat was commissioned to investigate the root causes. The firing system was evaluated using NIR thermography and the firing at the individual burners and the entire steam generator was optimized. Finally, optimized process operating parameters were derived from the results and provided to the Client for implementation in the steam generator control system. The root causes of corrosion could thus be successfully eliminated.
