Abstract


In today 's market economy under the conditions of the nuclear power plants have invested in merchant shipping , the best possible improve the economics of nuclear power plant , help to reduce the production costs of nuclear power plants , nuclear power plants to improve the market competitiveness . Nuclear Steam Turbine economy to some extent reflects the economics of nuclear power plants , and to clarify the the Nuclear Steam initial and final parameters of the impact of changes in the economics of nuclear power turbine heat and help to improve the market competitiveness of nuclear power plants , the development of low-carbon economy building a harmonious society is of great significance . First of all, we proceed from the conventional heat balance method to calculate the heat of nuclear steam turbine regenerative system analysis , based on the coupling between the nuclear power turbine reheat system with heat recovery systems , thermodynamic calculation of the nuclear steam turbine regenerative system for solving equations , this article iterative method by means of numerical analysis , proposed a C programming language for solving equations and the final completion of the regenerative easy way calculated to verify the accuracy of this method through examples . Second, nuclear power turbine early end of parameter changes in the analysis , and nuclear power turbine early end parameters , respectively, change , nuclear power turbine impact process conducted analysis , according to the Nuclear Steam various hot economic nature indicators of calculation formula , derivation of the beginning of the final simple calculation method of parameter changes affect the economy of nuclear power turbine heat . Finally, a 990MW nuclear power steam turbines beginning of the end of parameter changes caused by the nuclear steam turbine the ideal internal power ideal cycle thermal efficiency , heat consumption rate of the relative change in the rate of simple calculations , using traditional heat balance method for nuclear power steam turbine heat recovery system derived the corresponding relative rate of change compared to verify the accuracy of the easy way on the initial and final parameter changes in the economy of nuclear power turbine heat .
