The article considers a promising steam-turbine heating plant, which includes a steam turbine with back pressure and a steam boiler operating on natural gas, with waste heat recovery. 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 technological scheme, as well as fuel costs in each characteristic mode of operation have been found by the criterion of the minimum price of electricity. The considered steam-turbine heating plant provides a higher heat utilization coefficient of the fuel than the traditional heating plant.
