Abstract

Leakage on the tube is one of the damage that often occurs in the High Pressure Heater. One way to deal with leakage tubes in High Pressure Heater is by plugging the end of the leaked tube with a plug so that the tube does not flow with water. Plugging is done because the required maintenance time is less than retubing or replacing a leaky tube with a new one. However, plugging is done on the High Pressure Heater has a maximum limit. If plugging exceeds the maximum limit, the High Pressure Heater will experience a decrease in performance, so it needs to be retubed. Provision of plugging is expected to reduce the rate of heat transfer from the High Pressure Heater. High Pressure Heater 5 units 3 PLTU PT. Indonesia Power UP Suralaya retubed or replaced the tube in October 2019. Descriptive and quantitative methods are based on field case studies in High Pressure Heater 5 Suralaya Unit 3 PLTU and are strengthened with several theories and scientific journals. The data used in this study were obtained from several related parties namely CCR (Central Control Room) Unit 3 and 4 Suralaya Power Plant, and Turbine Maintenance Unit 1-4 PLTU Suralaya. The purpose of this study was to determine the performance of the High Pressure Heater before and after retubing. After retubing, there was an increase in the value of the Heat Transfer Rate in the Desuperheating, Condensing, and Subcooling zones by 202,67 kW, 1119,87 kW, and 604,11 kW. The value of the total heat transfer rate has increased from 31865,15 kW to 33791,8kW. The results obtained in this study from the calculations that have been done by comparing between before and after the replacement of HPH 5 is the performance of HPH 5 improved after retubing because there is no more plugging in the HPH 5 tube Keywords: High Pressure Heater, retubing, plugging, heat transfer rate Kebocoran pada tube adalah salah satu kerusakan yang sering terjadi pada High Pressure Heater. Salah satu cara untuk mengatasi kebocoran tube di High Pressure Heater adalah dengan cara plugging atau menyumbat ujung tube yang bocor dengan plug agar tube tidak teraliri air. Plugging dilakukan karena waktu maintenance yang dibutuhkan lebih sedikit dibanding retubing atau mengganti tube yang bocor dengan tube yang baru. Namun, plugging yang dilakukan pada High Pressure Heater memiliki batas maksimum. Jika plugging melewati batas maksimum maka High Pressure Heater akan mengalami penurunan performa sehingga perlu dilakukan retubing. Pemberian plugging diduga akan menurunkan laju perpindahan panas dari High Pressure Heater. High Pressure Heater 5 unit 3 PLTU PT. Indonesia Power UP Suralaya dilakukan Retubing atau penggantian tube pada bulan Oktober 2019. Metode deskriptif dan kuantitatif yang didasarkan pada studi kasus lapangan pada High Pressure Heater 5 PLTU Suralaya Unit 3 dan diperkuat dengan beberapa teori dan jurnal ilmiah. Data yang digunakan dalam penelitian ini dapatkan dari beberapa pihak terkait yaitu CCR (Central Control Room) Unit 3 dan 4 PLTU Suralaya, dan Pemeliharaan Turbin Unit 1-4 PLTU Suralaya.Tujuan dari penelitian ini adalah untuk mengetahui performa High Pressure Heater sebelum dan sesudah retubing. Setelah dilakukan retubing terjadi kenaikan nilai Laju Perpindahan Panas pada zona Desuperheating, Condensing, dan Subcooling sebesar 202,67 kW, 1119,87 kW, dan 604,11 kW. Nilai laju perpindahan panas total mengalami kenaikan dari 31865,15 kW menjadi 33791,8 kW. Hasil yang didapat pada penelitian ini dari perhitungan yang telah dilakukan dengan membandingkan antara sebelum dan sesudah penggantian HPH 5 adalah performa HPH 5 meningkat setelah dilakukan retubing karena tidak ada lagi plugging di tube HPH 5. Kata kunci: High Pressure Heater, retubing, plugging, laju perpindahan panas
