摘要:A power plant was analyzed in this paper, consisting of the following installations: a hard-coal-fired pulverized fuel boiler, a steam turbine, a CO 2 capture unit and an air separation unit equipped with a four-end-type high-temperature membrane and a gas turbine. The gross electrical power of the power plant is 600 MW; the live steam parameters are 650°C/30 MPa and reheated steam parameters are 670°C/6 MPa. The total investment cost of analyzed power plant was shown. An economic analysis of the plant was performed, using thermodynamic indicators such as net efficiency of electricity generation and auxiliary power rate of the power plant for oxygen recovery rate equal to 80%. A break-even price of electricity was used as an economic indicator. The paper presents results of the calculations. An analysis of economic risk using Monte Carlo method was performed. This paper presents a methodology of the analysis along with the results in the form of graphs of incidence (histogram) and cumulative probability (cumulative distribution function) of break-even price of electricity. Additionally, an analysis of the influence of individual random variables on this break-even price was presented.
