Abstract

This study examines the decline in boiler performance, highlighting the imperative of efficient maintenance to prevent operational disruptions and financial losses. The focus is on the analysis of boiler functionality, identifying factors that contribute to reduced efficiency and increased downtime. Utilizing performance data from August 2023, the research documents a significant downtime of 4610 minutes, primarily attributed to mechanical issues and extended recovery periods totaling 1920 minutes. The study also reports a high fuel usage efficiency ratio of 35 Kg/cm3, underscoring the challenges in initial recovery efforts. Despite these setbacks, machine quality metrics indicated no defects, suggesting effective quality control measures. The findings underscore the critical relationship between maintenance strategies and boiler efficiency, proposing that proactive maintenance could mitigate downtime and enhance productivity, thereby supporting sustained operational efficiency. Highlights: Maintenance crucial for boiler efficiency and cost savings. Downtime leads to production delays and financial losses. Performance metrics indicate operational reliability and effectiveness. Keywords : Boiler, Maintenance, Operating Time

Abstract

General Background Condensers play a crucial role in thermal systems by converting steam into liquid through heat transfer processes. Specific Background The performance of condensers is influenced by key parameters such as pressure, temperature, and fluid flow rate, particularly in finned tube systems. Knowledge Gap Previous studies have examined general condenser performance, but limited research has focused on Pokka 5001 type condensers with louvered fins under varying pressure conditions. Aims This study aims to analyze the efficiency and heat transfer rate of a Pokka 5001 condenser using pressure variations as the primary variable. Results Experimental results show that increasing pressure from 20 to 40 Psi leads to higher efficiency values, ranging from 73.17% to 89.68%, and improves heat transfer rate and fluid work. Additionally, higher flow rates contribute to increased heat transfer performance. Novelty This study provides experimental evaluation of a Pokka 5001 finned tube condenser with controlled pressure variation and airflow conditions. Implications The findings support better operational control of pressure and flow rate to maintain optimal condenser performance in thermal systems. Keywords: Condenser Pressure, Heat Transfer, Efficiency Analysis, Finned Tube, Thermal System Key Findings Highlights Efficiency increases consistently with rising operating pressure Flow rate growth correlates with higher thermal transfer performance Experimental data identify optimal operating conditions
