Gemilerde Kullanılan Termik Yağ Sisteminin Performans Analizleri

Öz

Enerji verimliliği günümüzde giderek önem kazanmaktadır. Enerji verimliliğinin arttırılması ile yakıt tüketimi ve çevreye zararlı olan etkileri azaltmak mümkün olmaktadır. Ayrıca yakıt fiyatlarının önümüzdeki yıllarda artan trend göstermesi öngörülmektedir. Gemilerde uygulanan enerji verimliliği uygulamalarında enerji kaybının yaklaşık %25'ini oluşturan ekzoz gazından enerji kazanım yöntemleri öne çıkmaktadır. Gemilerde atık egzoz baca gazı enerjisini geri kazanmak için ekonomizer kullanılmaktadır. Bu çalışmanın amacı, ekonomizer ana kazanın ön ısıtıcısı olarak çalışırken, termik yağ sisteminin performans, maliyet ve çevresel etki analizlerini gerçekleştirmektir. Bu kapsamda ana makinesi 4350 kW, kazanı 1500 kW ve ekonomizeri 340 kW olan bir gemi ele alınmıştır. Sonuç olarak, incelenen sistemde, termik yağ olarak Syltherm XLT ve yakıt olarak da VLSFO’nun kullanılması ile hem yakıt maliyeti açısından tasarrufun sağlandığı hem de SOx salımlarının azaldığı görülmüştür.

Performance Analyses of Marine Thermal Oil System

Energy efficiency is getting more and more important nowadays. By increasing energy efficiency, it is possible to reduce fuel consumption and harmful effects on the environment. In addition, fuel prices are expected to show an increasing trend in the coming years. In energy efficiency applications applied on ships, energy recovery methods from the exhaust gas, which constitutes approximately 25% of energy loss, come to the fore. Economizers are used to recovering the waste exhaust flue gas energy in ships. The aim of this study is to perform performance, cost, and environmental impact analyses of the hot oil system while the economizer is working as the preheater of the main boiler. In this context, a ship with the main engine (4350 kW), boiler (1500 kW) and economizer (340 kW) is considered. As a result, it has been observed that the use of Syltherm XLT as thermal oil and VLSFO as fuel in the examined system provides both savings in terms of fuel costs and reduced SOX emissions.
