Abstract

Steam Power Plant has one of the main components, namely the Boiler. Boiler is a machine that functions to convert water into steam. The boiler used by PLTU PT X uses a CFB type boiler. When the boiler works to convert water into steam, it is identified that heat loss occurs and when the site test uses the calorific value of coal it is different from the design so that it affects the efficiency of the boiler. The purpose of this study is to determine the heat loss that can affect the performance of the boiler and get a more efficient boiler performance. The method used in this study is a direct and indirect method where the method uses the steam property software or steam table and The Sugar Engineers Psychrometric calculation. The standard for calculating boiler efficiency used is ASME PTC 4.1 Power Test Code Steam Generator Units. The results of this study indicate that the boiler efficiency with the direct method is 81.68% at the site test and 83.85% at the design time. design so that the use during the Design conditions is more efficient than during the site test conditions and it is observed based on the two tests that the largest heat loss that can affect the performance of the boiler working efficiency is to convert water into steam, namely moisture in fuel. Keywords: CFB Boiler, Efficiency, Direct Method, Indirect Method Pembangkit Listrik Tenaga Uap mempunyai salah satu komponen utama yaitu Boiler. Boiler merupakan suatu mesin yang berfungsi untuk mengubah air menjadi uap. Boiler yang digunakan oleh PLTU PT X menggunakan Boiler tipe CFB. Pada saat boiler bekerja mengubah air menjadi uap teridentifikasi terjadinya kehilangan panas dan pada saat site test menggunakan nilai kalor batubara berbeda dengan design sehingga mempengaruhi kinerja efisiensi boiler. Tujuan penelitian ini adalah mengetahui Kehilangan Panas yang dapat mempengaruhi penurunan kinerja Boiler dan mendapatkan kinerja boiler yang lebih efisien. Metode yang digunakan dalam penelitian ini adalah metode direct dan indirect dimana metode tersebut menggunakan software steam property atau steam table dan The Sugar Engineers Psychrometric calculation. Standar perhitungan efisiensi boiler yang digunakan yaitu ASME PTC 4.1 Power Test Code Steam Generator Units. Hasil penelitian ini menunjukan bahwa efisiensi boiler dengan metode direct adalah 81,68% pada saat site test dan 83,85% pada saat design Sedangkan nilai perhitungan efisiensi boiler metode indirect adalah 82,43% pada saat site test dan 84,53 % pada saat design sehingga Penggunaan pada saat kondisi Design lebih efisien dibandingkan pada saat kondisi site test dan diamati berdasarkan kedua pengujian tersebut bahwa kerugian panas terbesar yang dapat mempengaruhi penurunan kinerja efesiensi boiler bekerja mengubah air menjadi uap yaitu moisture in fuel.
