Implementation of Long-Term Performance Tests And System Optimization of Farm Type Biogas Plant
Project no. 670 · Status: Kapanmış · 2015
Summary
Biogas systems are economical and technically proven systems in terms of energy and organic fertilizer production and treatment. These systems, which are used in large scale in developed countries, are fully automated and highly efficient. But the initial investment costs are quite high. System automation has a large share in increasing these costs. However, when we look at biogas systems in developing countries, low-efficiency, small-scale and non-automated systems are emerging. The reason for the small scale of the system is that the animal distribution is around 5-50 per farm and there are logistical problems among farms. When low purchasing power is added to this, unfortunately low-yielding primitive biogas systems constitute the majority. Although our country is far ahead of the countries we have mentioned in terms of development, it provides relatively little opportunity for large scale systems due to the reasons such as territorial division and lack of organization. Therefore, the development of small and medium-sized efficient biogas systems by the domestic industry and R & D organizations is gaining importance in terms of the widespread of these systems. Within the scope of this project, the effects of automation of a biogas system to meet the energy needs of a farm with 25 cattle were investigated on system efficiency and cost. Within the scope of the Ministry of Development project carried out by Ege University Solar Energy Institute, the work on the biogas system established in Torbalı was continued. The system is a semi-automated system. The advantages of automation on the efficiency of this system are discussed. In the transition from semi-automation to full automation, system installation and operation costs increased by 30-60% in today's market conditions. On the other hand, it is concluded that biogas production efficiency is much less than this rate. This low savings/cost ratio of fully automated systems suggests that semi-automated systems are more advantageous for rural areas in today's conditions. The most important factor here is that the software and sensors for automation are still not produced in the domestic industry and therefore increase in costs. In the case of resolution of these problems, fully automated biogas systems will be able to reach the position they deserve in our country.
