Organic rankine cycle (ORC), special fluids are used which can evaporate at relatively low temperature instead of water as the vehicle fluid. In this way it is possible to produce electricity from waste heat sources at low temperatures. In this study, it was investigated that the required thermal energy for the ORC was achieved by burning gases in a combustion chamber (Flare) in a low-emission hot water boiler. The electricity generated at the end of the cycle is theoretically calculated. The main components of the system are the boiler, turbine, and cooling unit has been examined. Cost, feasibility and emission analyzes of the system are made; according to TURKEY and USA conditions, the repayment period and internal rate of return are calculated. As a result of the application, it is seen that electricity production can be done at 76,5 kWe power from 118 Nm3/h waste gas.

In recent years, Turkey’ energy consumption has increased with the increasing rate parallel to the growth rate. For this reason, the importance of efficient use of energy has become more and more remarkable every day. In this study, the potential of ability to the work by the control and automation of the electrostatic powder coating system in a sample operation is increased. In addition, efficiency has been ensured in terms of natural gas consumption and electricity consumption. In terms of the coating operation, the amount of dye consumed per unit m2 has been reduced and the operating costs have been reduced. In this context, surface cleaning, drying, dyeing and curing steps in the electrostatic powder coating cabinets in the dying cabinets have been transferred to the conveyor system. For electricity and natural gas consumption, the cost of energy consumption per m2 is calculated to produce unit work for energy efficiency. Feasibility studies were made for the facility and the system was installed. The simple payback period is calculated and the increase in the total efficiency of the system and the increase in capacity are presented.

ORC turbines, which have been developed for the production of electricity from low temperature thermal sources, have been used in high temperature applications in recent years together with the developing technology. These machines, which can generate heat and power, are the preferred technology for biomass power plants with high thermal efficiency rates. Biomass energy is a kind of cheap, clean and renewable energy whose existence dates back to years B.C. In this study, thermal oil obtained from biomass fired hot oil boiler in a factory and production of electricity and hot water from this thermal oil by ORC turbine were investigated.

In our growing and developing world , as a result of the continuous development of technology , more energy intensive living standards and ever-increasing demands for luxury living, the need for energy is increasing more and more. For this reason; especially EU countries, USA, Japan and all other countries in the world in general, aimed energy saving by linking energy supply / demand to legal legislations. While energy efficiency applications ongoing in the world , as Turkey imports almost 75% of its primary energy need , it creates a heavy burden on the back of our country's economy. In our country , as a result of the fact that electricity and heating needs are met especially from natural gas and the existing energy potentials are not fully utilized, we import a large part of our energy needs. This, inevitably constitutes the main reason for our economic dependence on the outside and also constitutes the main factors that distract us from the principle of sustainability in terms of energy supply and security. For this reason; Turkey published in the Official Gazette No. 5627 dated 02/05/2007, energy efficiency main purpose of the law; is the disposal of waste energy by creating maximum energy saving models. In addition, our priority national goal in producing recoverable and / or clean energy is to promote the conscious use and consumption of energy through out the country. As a result of all the productivity increasing projects and works prepared in this context, it is aimed to reduce the energy intensity of our country and to decrease the energy cost in cumulative. For our country , the energy consumption intensity is around 39-40% for the industrial sector, and it is known that the building & housing level is 30% and above. With these figures , both the public life is affected negatively and this excess energy consumption rate destroys the natural balance and creates a risk for the whole life. As a result of the current researches of our energy intensity, it is 2 times higher than OECD countries, 2.5 times more than EU countries, 4 times more than Japan and approximately 1.5 times more than the world average, in general, for one unit energy we pay more compared to other countries. In this study, the current regulations that promote energy efficiency and related incentive projects have been examined within the framework of the energy efficiency law in our country and on the other hand, by drawing attention to the innovations introduced in both EU, USA and Japan interms of industrial efficiency, energy efficiency in the world and in our country.

Çalışma kapsamında mevcut kojenerasyon atık ısının kullanım potansiyeli araştırılmış ve tesiste kullanılan mekanik soğutucuların uygulama öncesi enerji tüketimleri ile soğutma yükleri belirlenmiştir. Mevcut mekanik soğutucuların yerine kojenerasyon atık ısısı kullanılarak absorbsiyonlu soğutuculara dönüştürülmesi ile elde edilecek tasarruf miktarı hesaplanmıştır. Nowadays, absorption cooling systems are gaining importance because of the excessive electricity consumption and the high energy costs of the cooling systems. Absorption cooling systems, which can use any type of heat energy as an external energy source and they are preferred for cooling and air conditioning applications because they do not need an additional energy source. In this study, it was aimed to increase energy efficiency by using cogeneration waste heat in an absorption chiller instead of using existing mechanical chiller in a chemical production plant. In the scope of the study, the usage potential of existing cogeneration waste heat was investigated and energy consumption and cooling loads of the mechanical coolers were measured in the pre-application period. The amount of energy savings was also calculated in the case of replacing existing mechanical coolers with absorption coolers by using cogeneration waste heat
