Selection and analysis of combined cogeneration plant of natural gas for heating the city of Bitola

The basis for initiating this research was based on the latest achievements in the development of energy technologies, such as: efficiency, energy saving and ecology. In this research, the findings from some previous research in this area had been used, especially for cogeneration plants with natural gas as an energy source for combined production of electricity and thermal energy. A selection of the drive motor in the plant cogeneration was done, depending on the defined needed heat for the city of Bitola. According the curve of the hourly temperature of the outside air for the city of Bitola and the heat consumption, analysis of the thermal cogeneration plants was made in terms of: combined steam-gas cycle to produce heat for heating in the range between (80-200) MWt and a cycle with steam turbine with regulated subtraction.
