The article analyzes the energy efficiency of several methods of entering make-up feed water into the CHPP cycle. The purpose of the work is to assess the influence of the mass flow rates of the make-up feed water into the cycle of CHPP on its energy efficiency. This goal is achieved through the use of an adapted mathematical model of the turbine unit T-50-130, on which computational studies of variable operating modes were carried out and a comparative assessment of the energy efficiency of supplying make-up feed water to the condenser and the pipeline of main condensate. The value of the generated electric power and the specific heat consumption for electric power generation were taken as the main criteria determining the efficiency of the turbine unit. The most significant result of the research is the establishment of the fact that it is the condenser that is the best place to enter makeup feed water into the cycle of a cogeneration turbine according to the criterion of energy efficiency. The highest energy effect can be obtained by supplying make-up feed water to the condenser in the heating mode. The significance of the results obtained lies in the fact that their practical use will significantly increase the energy efficiency of steam turbine plants by supplying make-up feed water to their condensers. The results obtained differ from the known ones in that for the first time such studies were carried out on an extended mathematical model of a steam turbine unit. |
