As a result of many applications in industrial plants and mechanical systems in public buildings, waste heat is generated, and significant amounts of energy and money can be saved by using this waste heat for different useful purposes in the enterprise before it is discharged into the atmosphere. In this project, the energy efficiency of the hot water boiler used in the heating system of the public building has been investigated. Within the scope of efficiency-enhancing applications, it has been determined at which rates savings will be achieved by utilising waste heat. The exhaust gases leaving the boiler at high temperature can be used in a heat exchanger and the waste heat can be utilised to heat the combustion air or feed water used in the boiler. The chimney of the hot water boiler system examined is proposed as economiser for heat recovery. Savings are achieved by not using fuel equivalent to the recovered energy. The cost analysis was calculated using the payback period method. Annual monetary savings of 29,049.0 USD/year were calculated in the economiser system. If economiser boiler is used in the public building, the payback period of the improvements will be 0.13 years.

Endüstriyel tesislerde birçok uygulama sonucunda ve kamu binalarında mekanik sistemlerde atık ısı meydana gelir ve bu atık ısının atmosfere atılmadan önce işletmede farklı faydalı amaçlar için kullanılması ile önemli miktarlarda enerji ve para tasarrufu sağlanabilir. Bu projede kamu binasının ısıtma sisteminde kullanılan sıcak su kazanının enerji verimliliği incelemesi yapılmıştır. Verim arttırıcı uygulamalar kapsamında atık ısıdan faydalanarak hangi oranlarda tasarruf sağlanacağı belirlenmiştir. Yüksek sıcaklıkta baca gazlarını bir ısı eşanjöründe kullanılıp atık ısı değerlendirilerek, kazanda kullanılan yakma havasının veya besleme suyunun ısıtılması sağlanabilir. İncelenen sıcak su kazanı sisteminin bacası ısı geri kazanımı yapılacak şekilde, ekonomizerli olarak önerilmektedir. Geri kazanılan enerjinin karşılığı kadar yakıt kullanılmayarak tasarruf sağlanmaktadır. Maliyet analizi geri ödeme süresi yöntemi kullanılarak hesaplanmıştır. Ekonomizerli sistemde yıllık 29.049,0 USD/yıl parasal tasarruf hesaplanmıştır. Eğer incelenen kamu binasında ekonomizerli kazan kullanılırsa, iyileştirmelerin geri ödeme süresi 0,13 yıl olacaktır.
