Abstract

This investigation concentrates on the enhancement of energy efficiency in a locally engineered steam boiler to address considerable energy losses linked to fossil fuel-based power generation. A thorough retrospective examination of boiler technology is offered, highlighting the intrinsic inefficiencies present in earlier designs. Employing Response Surface Methodology (RSM) alongside I-optimal design, this study rigorously evaluates essential operational parameters, such as steam inlet pressure, injection flow rate, and biomass utilization. The optimization procedure delineates the subsequent optimal parameters: a steam inlet pressure of 9.33 bar, a motor speed of 1226.15 rpm, and a biomass utility of 29.989 kg/h (comprising both firewood and rice husk). These configurations yield a peak efficiency of 74.093%, a steam injection flow rate of 246.037 cm³/s, and a steam production rate of 18.451 kg/h. The findings emphasize substantial potential for improving operational efficiency and minimizing emissions, thereby fostering more sustainable energy production methodologies. This research offers significant insights for engineers and scholars seeking to enhance the performance of biomass-based steam systems within the framework of renewable energy endeavours.
