Abstract
In this paper the recent development of the coupled simulation of large utility boilers is described. The coupled simulation is an advanced tool to investigate the interaction between the furnace and the steam cycle of power plants. Gained knowledge is useful both for design of future facilities and optimisation of operational performance of existing power plants. In this article the detailed simulation of a Triflux Heat Exchanger (THX) is presented. In utility boilers THX are used to exchange heat between the flue gas, the Superheater (SH) and the Reheater (RH) steam cycle. The presented methodology allows to calculate the steam and tube temperatures of all heated tubes of an utility boiler including the THX. Results and a comparison between measured and calculated values are presented for a lignite-fired boiler.
