The experience of Denmark, Finland and Russia shows that up to 90 % of the urban demand in heat and electricity can be provided in a joint cycle of their production. The European Union adopted a directive about the development of co-generation to a level of 10% of total electricity generation. From the point of view of the energy business there is valuable in big cities the presence of the combined networks of consumers who use both electricity and heat. Cogeneration systems of most Ukrainian cities are characterized by a high degree of deterioration of thermal power station and thermal networks. The heat consumption of the population is also reduced because of high tariffs for thermal energy. Main economic problems CHP manifested during reducing of the heat load and the corresponding increase in the cost of electricity. In terms of environmental safety of urban district heating it is advantageous. Therefore, the extension of exploitation of the heat power stations is actual and requires special studies. The geometric model of the high pressure rotor, based on visual inspection dates during the repair works, is building. To optimize the calculations in the model there were selected the regulating stage and the first four non-regulated stages of the high pressure rotor, where the metal temperature is high and we have the maximum temperature gradients in the starting regimes. The boundary conditions during the starting from the cold, non-hot and hot states were calculated. When calculating the boundary conditions the changes of the working parameters are were taken into account.
