Thermoeconomic Optimization of a 1000MW Coal-Fired Unit

Article Preview

Abstract:

In order to decrease the operation cost of a power plant, a 1000MW coal-fired power plant is studied as the research objective, and an evaluation model about unit thermoeconomic cost is built based on the thermoeconomic theory. By using the Matlab calculation tool, the thermoeconomic optimization of the energy system about the plant is presented. The results show that it is necessary to update the correlated equipment to increase its exergy efficiency in the design of the entry unit. Moreover, the exergy efficiency of the boiler is close to the optimum value, as for the steam turbine, its efficiency can be increased with the increment of investment.
