Abstract
In the paper presented is a concept to utilize waste heat from the power plant with the aid of the low-temperature ORC cycle. The ORC system is heated from two heat sources, the first one being the flow rate of waste heat obtained from the exhaust gases. Subsequently, the working fluid in the cycle is additionally heated by the condensing steam from the low pressure turbine extraction points increasing in such way the level of temperature of working fluid before turbine to 120stC. Examination of the results enables to conclude that the overall efficiency of the cycle increased from η=51.958% to η=52.304%. That is due to the fact that additional heat enabled to evaporate more working fluid. The total generated power increased to the value of Ne=915.85 MWe, which corresponds to about 1.5% increase in power.
