Abstract

Dalam suatu sistem Pembangkit Listrik Tenaga Uap diperlukan sebuah boiler dimana di dalam boiler ini terdapat suatu tingkatan-tingkatan yang terdiri dari tube-tube. Salah satunya disebut dengan final superheater. Pada final superheater terjadi perpindahan panas dari gas hasil pembakaran ke uap jenuh yang pada akhirnya uap jenuh tersebut diubah menjadi uap panas lanjut. Pada akhirnya uap panas lanjut tersebut digunakan untuk memutar turbin uap. Dalam tugas akhir ini akan dihitung nilai laju perpindahan panas (q) dan koefisien perpindahan panas (U) pada final superheater. Selain itu juga akan diketahui luas bidang permukaan perpindahan panas seluruhnya (A) pada final superheater. Awalnya dapat diketahui laju perpindahan panas yang terjadi (q) dari laju aliran massa uap masuk final superheater. Dan selanjutnya untuk mencari nilai (U) sebelumnya harus diketahui besaran nilai koefisien konveksi di dalam maupun di luar tube. Setelah diketahui dua besaran tersebut, kita juga perlu mengetahui jenis material tube yasg dipakai dan juga fouling faktor di dalam dan di luar tube. Setelah (q) dan (U) diketahui dapat dicari nilai (A) dimana (A) adalah nilai luas bidang permukaan perpindahan panas seluruhnya. Dengan diketahuinya (A) dan (U) dapat dihitung panjang pipa tiap laluan (L). Dari perhitungan diatas, maka didapat nilai U = 2,29U/m^2K. Dan besarnya perpindahan panas yang terjadi diketahui sebesar q = 582.350,34 W. Maka nilai A diketahui 3.272,403m^2. Sehingga panjang pipa tiap lahuan (L) adalah 2,1 m.

In the Steam Powe Plant Electric System, there needed boiler where in each boiler consist of many tubes. One of them was named superheater. In final superheater, there was heat transfer from gas as result of combustion into saturated steam then finally from that saturated steam could be changed into superheated steam. In the end, the superheated steam could be used to rotate steam turbin. In this final project, there would be calculated rate value of heat transfer (q) and heat transfer coefficient (U) in final superheater. Not only that but also it could be known the width of total heat transfer surface (A) in final superheater. From beginning, it could be known heat transfer rate (q) from steam mass flow went to final superheater. Next, to seek (U) value, it must have been known before the convection coefficient quantity inside or outside the tube. After both of them werw known, we needed to know the material tube type which was used and fouling factor inside or outside tube. After (q) and (U) had been known, the we must have been looked for (A) value, (A) was total heat transfer surface. After (A) and (U) werw known, the length of inlet bush (L). From the calculation above, it could be got U value = 2,29U}/m^2K and sum of heat transfer was q = 582.350,34 W. A value was 3.272,403m^2. So length of inlet bush was 2,1 m.
