Design and exergy analysis of a thermal power plant using different types of Turkish lignite

Öz:

Bu çalışmanın amacı 240 $MW_{el}$ gücünde, farklı on Türk linyiti ile çalışacak bir termik santral (TPP) tasarlamak ve her bir linyit tipi için başaranını (performans) belirleyen ve karşılaştıran ekserji analizini yapmaktır. İlaveten çevre sıcaklığının santralin ekserji verimine etkisi incelenmiş ve her linyit tipinin atmosfere bıraktığı $CO_2$; sera gazı miktarı hesaplanmıştır. Her bir birleşenin ekserji tüketişi devamlı rejimde kütle ve enerji salanımı yasaları ve ekserji tüketimi bağıntısı kullanılarak incelenmiştir. Tasarım için Sivas Kangal linyiti seçilmiş. Santralin net enerji ve ekserji verimleri 37.16 ve 34.84 olarak hesaplandı. Bu şartlardaki analiz göstermektedir İd başlıca ekseıji kaybı kazandadır, 299.10 MW ekseıji kaybı ve toplam ekserji kaybının % 83.29 u ile. Diğer bir nokta, çevre sıcaklığının artmasıyla yakıt tüketiminin ve $C0_2$ salınımının artmasıdır. Belirtmek gereldr ki santrallerin başaranının ve salınım bilgilerinin karşılaştırılması Türkiye'de gelecekte kömürlü termik santrallere yapılacak yatırımlar için yararlı veriler oluşturabilir.

Farklı Türk linyitleri kullanacak bir termik santral tasarımı ve ekserji analizi

Öz:

The purpose of this study is to design a 240 $MW _{el}$ thermal power plant (TPP) to be operated with ten different types of Turkish lignite and fulfill an exergy analysis including the determination and comparison of the performance for each type of lignite. Additionally an examination of the effect of the ambient temperature on the power plant’s exergy efficiency and calculation of the $CO _2$ emissions of each lignite type is carried out. Exergy destruction of each component is investigated by using conservation of mass, conservation of energy and exergy destruction in an open system at steady state. Sivas Kangal lignite is selected for designing. Net energy and exergy efficiencies of the plant are calculated as 37.16 and 34.84 % respectively. The analysis of the case study revealed that the boiler is the major source of exergy destruction with 299.10 MW and 83.29 % of the total exergy destruction of the overall plant. Another point is that, fuel consumption and $CO _2$ emissions of the TPP increase with rising ambient temperature. It should be noted that, comparison between the performances and emission data of the power plants can provide useful data for the future coal-fired thermal power plants investments in Turkey.
