Bir Kömür Santrali Konveyör Hattının Sismik Davranışının İncelenmesi

Öz

Hammaddeleri depolama alanından tesis içine taşıyan konveyör hattı, bir kömür santralinin ana damarıdır. Bu nedenle kritik öneme sahip bu hat, santralin kesintisiz çalışabilmesi için sahada maruz kalması muhtemel birçok yük dikkate alınarak tasarlanmalıdır. Bu çalışmada, bir konveyör hattı konstrüksiyonunun sismik davranışı Sonlu Eleman Analizi kullanılarak incelenmiştir. Türkiye, Adana'da faaliyet gösteren bir kömürlü termik santralinin kömür taşıyıcı konveyör hattının yapısı örnek olay olarak ele alınmıştır. Çalışmada, konveyör hattının parçaları 1-B olarak modellenmiştir. Gölcük-1999 depreminin ivme geçmişi değiştirilerek yapıya yanal yönden uygulanmıştır. Sonuçlara göre maksimum gerilmenin çeliğin elastik sınırından biraz daha yüksek ve nihai dayanımdan daha düşük olduğunu göstermiştir. Konveyör hattının konstrüksiyonu uygulanan yüklere dayanmasına rağmen konstrüksiyona zarar vermemek için modifikasyon yapılmalıdır.

Investigation of Seismic Behaviour of a Construction of a Conveyor Line in a Coal Power Plant

Öz

The conveyor line that carries raw materials from storage area to inside of a facility is the main vessel of a coal power plant. Therefore, this critical line should be designed by considering the many loads likely to be exposed in the field in order for the plant to operate uninterruptedly. In this study, seismic behaviour of a construction of a conveyor line was investigated by using Finite Element Analysis. The structure of coal carrier conveyor line of a coal power plant, operating in Adana, Türkiye was considered as a case study. In the study, the parts of the conveyor line were modelled as 1-D. The modified acceleration history of Golcuk-1999 earthquake was applied on the structure on lateral direction. The results showed that the maximum stress is slightly higher than the elastic limit of the steel and less than the ultimate strength. Although the construction of the conveyor line withstands the applied loads, modification should be carried out to prevent the damage on the construction.
