Abstract


This article presents the o-design operation of a 900 MW-class steam turbine cycle upgraded with utilization of lowtemperature
waste heat taken from boiler flue gas. The low-temperature heat contributes to increasing the eciency of
power plants without introducing many complex changes to the whole system. The base for investigations was a power
unit operating in o-design conditions and supplied with steam from a BB–2400 boiler. Modifications to the model were
made using commercially available software and by applying the Stodola equation and the SCC method. Calculations
for o-design conditions show that, after making some modifications to the system, both heat and electricity generation
could be increased through the addition of a low-temperature heat exchanger.
