Thermodynamic analysis of Batman waste water plant cogeneration system

Recently, as a result of the rapid rises in technology and problems such as war and disease, huge energy crises have emerged in developed-developing countries. The difficulty of accessing fossil resources and the magnitude of the damage caused by these resources to the environment have further increased the demand for renewable energy. Biogas is a renewable energy source that is formed by the biodegradation of organic materials, which we call biomass, in the absence of oxygen. Increasing energy efficiency is of great importance in the world where there is a great competition in meeting energy needs. For this reason, it is possible to obtain high efficiency in systems where Biogas is used, as in other energy sources, and to use the capacities of devices and equipment correctly, by calculating energy and exergy analyzes with precision. In this thesis, the energy analyzes of the cogeneration system established to use the Biogas obtained from the Waste Water Treatment Plant (WWTP) field established by Batman Municipality as an energy source are given. In the thesis, the effects of parts of the WWTP system on biogas production are shown in detail and schematically. In order to meet the electricity-heat need in the cogeneration system in an uninterrupted, high quality and clean manner, a 0.530 MWe GUASCOR FGLD 360 type engine with biogas fuel was used. With the realization of the combustion process, electrical energy is produced in the engine, and at the same time, hot water is obtained from the exhaust chimney and the engine jacket. The efficiency of the engine in the cogeneration system, exhaust emissions, exhaust gas temperature and electricity production in March, April and May were examined. For this purpose, I. and II. for each equipment in the system. Law analyzes are defined in the EES program. As a result of the calculations, the cogeneration system are 35.8 % and II. Law regulations are 41.3 %, and the total system is I. and II. Law efficiencies were obtained as 69.4 % and 45.7 %, respectively.
