Abstract

Boiler is one component that is widely used in the energy generation industry and reactors. One of the main components of the boiler is the boiler pipe. In field activities, there was a leak in the boiler pipe which experienced corrosion and erosion of the walls of the pipe. This condition results in a decrease in power and capacity in the boiler. The purpose of this practical work is to observe the causes of damage to the boiler pipe, and provide recommendations for prevention due to damage to the boiler pipe. The methods used are: literature study, observation, interviews, and measurement. The results obtained: (1) The calculation results show that the value of the Reynolds number obtained is 16,032,025.86 (Re>4000, turbulent flow). (2) The cause of corrosion on the boiler pipe is due to liquid droplet impingment which is accompanied by an increase in flow velocity and the occurrence of two phases (steam and water) thereby accelerating depletion in the boiler.

Abstract

This research aims to analyze the efficiency of steam consumption in the Dryer Section at the Paper Machine. The research method involves calculating the actual steam consumption efficiency and comparing it with the TAPPI efficiency standard. The research results show that the average steam consumption efficiency for grade W/FIPF35-70 reached 94.51%, exceeding the TAPPI standard of 86%. However, some observations indicate substandard results, which can be caused by factors such as raw material quality, process settings, and equipment wear. The conclusions of this research provide insight into the factors that influence steam consumption efficiency, providing a basis for improving performance in Dryer Section Paper Machine.

Abstract

This study conducts a comprehensive analysis of bearing failures in centrifugal pumps, aiming to find bearing life & the cause of difference in field data. Through meticulous examination of failed bearings, the research identifies root causes, including factors such as misalignment, inadequate lubrication, and excessive loads. The investigation involves a series of systematic steps to identify, evaluate, and understand the causes and impacts of damage that occurs. First, a visual survey of the centrifugal pump is carried out to look for physical signs that indicate damage to the bearing. This involves checking general conditions, such as wear, cracks, or leaks. The findings contribute to the nominal bearing life is 26.631,8 hours or about 3 years of use & the difference in life calculations between theoretical calculations and data found in the field is generally caused by high temperatures and vibrations in the bearing.
