Politecnico di Milano MSc. Energy Engineering – Power Production Energy Conversion A Prof. Gianluca Valenti PROJECT 4 COMPARISON OF ADVANCED STEAM CYCLES a.y. 2015/16 Giulia Boschi Omar Brembilla Alessandro Mosca 2 In this project, we are given six different configurations of USC steam power plants, named from A to F, all differing in some technical details. With the aid of the given software CicVap, we are able to run the plant simulation, perform the entropy analysis of the cycle and at last to com pare and comment on the results. Regarding the simulation part, we want to remind that all the data given in the text can be applied to our problem simply following the software instructions and changing the working parameters of the cycle. This is true except for the economizer inlet temperature. There is no such control variable in the software, so we have to satisfy our constraint changing the strictly related parameters, which are the condensation temperatures of all the bled streams, also considering that we want an almost constant temperature jump on the feed-water side of each preheater. Changing iteratively these condensation temperatures, we can get to a configuration that is the closest possible to the given one. For example, in case A we stated the following condensation temperatures: T.V.p-p(øC) Spill. nø 1 70.00 Spill. nø 2 102.00 Spill. nø 3 134.00 Spill. nø 4 167.00 Spill. nø 5 206.00 Spill. nø 6 240.00 Spill. nø 7 278.00 Spill. nø 8 311.00 And we got as economizer inlet temperature: T eco = 314.74 øC Using such process for all the configurations we have, we ran the software and obtained the cycle simulations (see Appendix). 3 0 0,1 0,2 0,3 0,4 0,5 0,6 0,7 A B C D E F 2ND - LAW EFFICIENCY [-] CONFIGURATION ENTROPY ANALYSIS Combustion Heat Introduction Tinf -…
