Sürdürülebilir Enerji Üretimi için Atık Isı Kullanımı ve Güneş Enerjisi Santralinin Karşılaştırması

Öz

Aynı bölgede atık ısı kullanarak elektrik üreten bir buhar türbini sistemi ile güneş enerjisi santrali (GES) arasındaki enerji üretimi karşılaştırılmıştır. Bu çalışma, her iki sistemin potansiyel enerji üretimini analiz etmeyi ve yatırım değerlendirmesi yapmayı amaçlamaktadır. Buhar türbini sistemi, endüstriyel tesislerde, fırınlarda üretilen atık ısıdan elektrik üreterek enerji verimliliğini artırmaktadır. Atık ısının mevcudiyeti ve miktarı, kullanılan yakıt türlerine bağlıdır; doğal gaz ve petrokok yaygın olarak kullanılmaktadır. Petrokok, daha fazla atık ısı üretirken, doğal gaz daha temiz bir yakıt olup daha düşük miktarda atık ısı üretmektedir. Bu değişkenlik, elektrik üretimini etkilemekte ve günlük ortalama 7,52 MWh üretim sağlanmaktadır. Buna karşın, güneş enerjisi santralleri sürdürülebilir ve yenilenebilir olup, genellikle daha düşük başlangıç yatırımı gerektirmektedir. Güneş enerjisi üretimi, coğrafi koşullar, güneş ışığına maruz kalma süresi ve panel verimliliği gibi faktörlere bağlıdır; ancak üretim kapasitesi sabit olup çevresel koşullar ve günün saatine bağlı olarak değişkenlik gösterebilmektedir. Her iki sistem de geri ödeme süreleri ve enerji üretim kapasiteleri açısından değerlendirilmiştir. Buhar türbini sistemi, büyük tesislerde sürekli atık ısının sağlanması ile istikrarlı üretim sunarken, verimliliği yakıt türlerine bağlıdır. Güneş enerjisi santralleri ise daha düşük başlangıç maliyetleri ve kısa geri ödeme süreleri sağlamakta, ancak çevresel faktörlerden etkilenebilmektedir. Çalışma, her iki sistemin de kendi avantaj ve dezavantajlarına sahip olduğunu ve en uygun sistemin yerel enerji ihtiyaçları ve çevresel koşullara göre seçilmesi gerektiğini vurgulamaktadır.

A Comparative Study of Waste Heat Utilization and Solar Power Plant for Sustainable Energy Production

Öz

A comparison of the energy production from a steam turbine system utilizing waste heat and a solar power plant (SPP) in the same region was conducted. The study aims to analyze the potential energy production of both systems and evaluate investment viability. The steam turbine system enhances energy efficiency in industrial facilities by generating electricity from waste heat, which is produced during furnace operations. The waste heat availability and quantity depend on fuel types, with natural gas and petroleum coke commonly used. While petroleum coke produces more waste heat, natural gas is cleaner but generates less. This variability impacts electricity production, with an average daily output of 7.56 MWh. In contrast, solar power plants are sustainable and renewable, typically requiring lower initial investment. Solar energy production depends on factors like geographical conditions, sunlight exposure, and panel efficiency, with fluctuations in output due to varying environmental conditions. Both systems were evaluated based on payback periods and energy production capacities. The steam turbine system offers stable production in large facilities with continuous waste heat, but its efficiency depends on fuel types. Solar power plants provide lower initial costs and shorter payback periods but can be affected by environmental factors. The study concludes that each system has its own advantages and disadvantages, and the most suitable system should be chosen based on local energy needs and environmental conditions.
