| description | Cogeneration is known as the generation of heat energy and electricity at same time by using the fuel's energy. There are various cogeneration systems, and steam injection is made into combustion chamber to increase the efficiency of the cycle and to reduce nitrogen oxide emissions. The most fundamental thermodynamic, operational, economical and thermo-economic factors must be considered when choosing the appropriate cogeneration system and designing the system. For the thermodynamic factors, such as the amount of fuel to be consumed, the electric heat rate, the artificial thermal efficiency, the fuel energy gain rate must be found for the unit amount of electric power to be obtained. The cost and availability of the fuel to be used must also be estimated by considering the problems will be affected by repair maintenance and economic fluctuations. In economic factors, the annual cash flow of the system and the amortization itself are calculated. In the thermo-economic factors, the investment costs depend on the exergy efficiency and the exergy of the products of the devices and the fuel required to operate are calculated. In this study, the analysis of steam injection into cogeneration systems according to performance and evaluation criteria was done using energy, exergy and economic methods. To calculate the energy and exergy values of the flows, a program was written by the authors in the FORTRAN programming language and the results obtained by running them were used. The results obtained were compared with the literature values and correctness was observed. |
