The mathematical model of а steam-turbine heating plant has been developed to perform one design calculation in the nominal mode and several verification calculations in characteristic modes with different thermal loads. Optimization calculations of the unit were carried out for two regions with different climatic conditions and different fuel prices. The optimal design parameters of the equipment, the parameters of the working fluid and coolants at all points of the ...
