| Abstract: | This paper obtains calculation of thermoeconomics in a 3# unit of the plant, determining all sub-system exergy efficiencies and distribution of exergy loss of devices, comparing with the results of thermal efficiency method, finding corresponding reasons and director of improvement. Finally, it presents optimization operation model of the boiler in efficiency maximum and preventing bird nest based on the neural network and genetic algorithm, directing operation of high efficiency and safety. |
