Anaerobic fermentation obtaining methane is applied in sludge stabilization processes. Methane is used to generate heat as well as the electric current in the fuel cells systems, gas turbines or cogenerative engines characterized by the high temperature oxidation. High temperature oxidation products (H2O, CO, CO2 and other flue gas) can be used in ORC cycles to generate the electric power. The following thesis presents the project of more efficient electric power generation system than the one used in the currently and based on cogenerative aggregates (piston engines). Models mentioned in the thesis:
- ORC cycle (Organic Ranking Cycle),
- gas turbine
- an anaerobic sludge stabilization system
The presented installation is more efficient in the electricity production (about 38%) than the traditional piston cogenerative engines used for biogas combustion (about 32%).
