| Abstract: | A linear model has been set up for calculating boiler heat absorption quantity, steam turbine power and condenser heat release quantity. An analysis of the role and effect of steam extraction and various additional steam/water components on the mass and heat energy balance of a thermodynamic system was performed. On this basis, obtained were a rapid model building method for determining the mass and energy balance of the double reheat supercritical unit as well as a method for the linear analysis of various additional components. As a result, a linear method is worked out for the comprehensive analysis and calculation of the boiler heat absorption quantity, steam turbine power and condenser heat release quantity of the double reheat supercritical power plant. |
