Abstract
PT. Indah Kiat Pulp & Paper Perawang is one of the largest pulp and paper industries in Indonesia that relies on mechanical equipment operating continuously, including the Induced Draft Fan (IDF B) as a vital component in the boiler combustion system. Homever, during operation, IDF B experiences probles in the form of high vibration and temperature levels, which cand potentially cause mechanical damage and disrupt the stability of the operational system.
This study ais to analyze the source of excessive vibration and temperature increase on IDF B. The methods used include vibration measurement with a vibration abalyzer, frequency spectrum analysis, and bearing temperature monitoring using a thermal camera and temperature sensor. The analysis result show that high vibration is caused by rotor mass imbalance, shaft misalignment, and potential bearing wear. Recommendations for improvement include shaft realignment, rotor rebalancing, and lubrication system improvement to mantain IDF B stable and efficuent performance.
