ANALISIS KINERJA BOILER PEMBANGKIT LISTRIK TENAGA UAP ASAM ASAM UNIT II – KALIMANTAN SELATAN

Abstract

This study aims to determine the value of commissioning boiler efficiency compared with current value and to know the causes of efficiency decrease in Unit 2 Boiler of Asam Asam Coal Fired Steam Power Plant. This research begins with collecting data of Performance Test during commissioning and current four years data from 2014 until 2018. Furthermore, heat losses that carried out are calculated and compared. Calculations performed using ASME PTC 4-2008 Standard Heat Loss Method. Based on the calculation results, it can be conclude that the highest HHV base Boiler Efficiency value in Unit 2 of Asam Asam Power Plant is 86.23% at Commissioning and the second highest HHV Base Boiler Efficiency value is 84.42% on August 9, 2017, while the lowest HHV base Boiler Efficiency is 82.12% on October 2, 2014. Heat loss that most affects the efficiency of Unit 2 Boiler is Heat Loss due to Heat in Dry Flue Gas (5.79% - 7.96%), Heat Loss due to Moisture in Fuel (4.07% - 5.57) %) and the Heat Loss due to Moisture from Burning of Hydrogen in Fuel (3.85% - 5.04%).
