Competitiveness of the combined production of chpp with the best available technologies for the separate production of electric energy and heat

Abstract

Further development of the Russian energy sector involves the use of the best available technologies. An important issue is the identification of bats. Increasing the fuel efficiency of power plants is carried out by increasing the unit capacity of generating equipment, increasing the parameters of the working medium to supercritical and super-supercritical. Unfortunately, when forming the list of bats, performance indicators are not always taken into account in real operating modes of the equipment. The calculations have shown that combined production of PTU-CHP plant with subcritical parameters of the working body on the basis of steam turbines of the type P, T and PT given the mandatory process releases steam into the condenser and the gas turbine CHP based on gas turbines of a small capacity has the best specific fuel consumption for generation of electric energy and heat compared to the separate generation of the best available technologies (BAT).
