Power industry is the basic industry of national economy, the level of development of power industry development in all walks of life directly affects the power production level is a measure of the importance of a country's economic indicators, per capita consumption is an important measure of living standards indicators. In this paper, 600MW steam turbine for thermal design, based on the known original data, select the type of turbine with steam institutional forms, flow section and the relevant parameters; proposed turbine thermal process similar to the curve, and the thermal economy of the preliminary calculations ; flow passage according to the shape and heat recovery steam extraction points required to determine the pressure level in the group stages and at all levels, lower than the enthalpy distribution, at all levels to conduct a detailed thermal calculations to determine the actual turbine heat process curve, according to the thermodynamic calculations, correction for the heat recovery steam heat process point pressure to conform to the requirements of the curve, and correct heat recovery system, heat balance calculations
