Abstract
Günümüzde hava kirliliği, insanlığın en büyük sağlık tehdidi haline gelmiştir. Endüstri kaynaklı ve özellikle fosil yakıtla çalışan enerji santralleri atmosfere önemli miktarda emisyon salınımı yapmaktadır. Birey başına düşen enerji tüketim miktarının artması da ortaya çıkan hava kirliliğinin artmasına sebep olmaktadır. Yakıt olarak kömür kullanan enerji santrallerinin atmosfere yaydığı kirlilikte en büyük paya sahip kirleticilerden biri partikül kirleticilerdir. Termik santrallerde proses sırasında oluşan partikül kirleticiler, emisyon kontrol teknolojilerinden biri olan elektrostatik filtreler (ESF) vasıtasıyla atmosfere yayılımı en aza indirilmektedir. Bu çalışmada, ESF verimliliğini arttırmak için operasyon parametrelerinde değişiklikler yapılarak filtrelerin partikül tutma verimleri incelenmiştir. Farklı kül değerlerine ve elementel analiz sonuçlarına sahip 3 kömür çeşidinin ESF verimliliğine etkisi gözlemlenmiştir. ESF performansını etkileyebilecek uçucu gaz sıcaklığı değerleri kullanılarak senaryolar oluşturulmuş ve bunların etkisine bakılmıştır. Uçucu gaz konsantrasyonuna direkt olarak etki eden farklı hava ön ısıtıcı kaçak oranları için toz emisyon değerleri hesaplanmıştır. Bununla birlikte, ESF sistemi içerisindeki süreçlerde oluşabilecek problemleri gözlemlemek ve elektrik tasarrufu sağlamak amacı ile elektriksel alanların bazı bölümleri devre dışı bırakılmıştır. Bu çalışmanın sonucunda, farklı senaryolarda ortaya çıkan partikül emisyon değerleri analiz edilmiş ve senaryolardaki değişkenlerin ESF verimine etkisi değerlendirilmiştir.
