Abstract

Boiler merupakan bejana tertutup dimana panas pembakaran dialirkan ke air sampai terbentuk air panas atau steam. Superheater merupakan alat yang berfungsi untuk menghilangkan kadar air dalam uap dengan cara menaikkan temperatur uap jenuh sampai menjadi uap panas lanjut (superheated vapour) yang kemuidan di uap panas lanjut ini di alirkan untuk memutar turbin. Mengetahui peran boiler yang penting bagi efisiensi siklus, maka perlu dilakukan analisis performa boiler pada PLTU Unit 4 untuk mengetahui rata-rata tingkat effectiveness tertinggi pada setiap pembebanan (50%, 75% dan 100%). Dengan demikian di ketahui efektivenes terbaik bada pembebanan tersebut. Berdasarkan hasil perhitungan dan pembahasan effectiveness Secondary Superheater, dengan data yang diambil dalam tugas akhir ini adalah data rata-rata kondisi aktual boiler kondisi sekarang. Sedangkan metode yang digunakan untuk menghitung laju perpindahan pans adalam dengan Number of Transfer Unit. Dari hasil hasil perhitungan diketahui bahwa ratarata tingkat effectiveness tertinggi berada pad pembebanan 50% dengan rata-rata nilai NTU 0,831003428, Cr 0,310407097 dan Cr 0,837685402. ================================================================================================================ Boiler is a closed vessel in which the combustion heat transferred to water until it becomes heated water or steam.Superheater is a tool that serves to remove the water content in the vapor by raising the temperature of saturated steam to be further hot steam (superheated vapor, which is then further steam is piped to turn turbines. Knowing that an important role for the efficiency boiler cycles, it is necessary to analyze the performance of the boiler at the power plant unit 4 to determine the average highest level of effectiveness in every load (50%,75% dan 100%). Thus to know the best effectiveness of the loading it. Based on calculation and discussions effectiveness boiler, with data taken in this thesis is the average data of actual boiler condition sekaran conditions. While the methods used to calculate the rate of displacement pans is the Number of Transfer Unit. From the results of the calculation result is known that on average the highest level of effectiveness is at a loading of 50% with an average value of NTU 0,831003428, Cr 0,310407097 and Cr 0,837685402.
