Carnotization
During the Carnotization of a thermodynamic cycle , it is approximated to the Carnot process and thus optimized.
This is done in the steam power plant by preheating the feed water in different stages with the help of smaller amounts of steam , which are taken from the turbine or exhaust gases from the steam heater . Due to the higher inlet temperature of the water in the steam boiler , the mean temperature difference between the heat transfer from the flue gas to the water is lower, which results in a lower exergy loss and thus a higher efficiency of the process.
In the gas turbine process, Carnotization is achieved by cooling the air between the compressor stages and by heating the working gas in combustion chambers between the turbine stages. The process is thus approximated to the Ericsson cycle , which as an ideal comparison process is equivalent to the Carnot process.
