Design and Fabrication of a Steam Boiler

Abstract

This research is focused on the design analysis of a steam boiler. The findings presented in this project highlight the significance of considering multiple factors, such as thermal efficiency, material properties, and safety features, in the design and fabrication of steam boilers. The intricate challenges of a functional and efficient steam boiler system were successfully explored and addressed. The results of detailed design, accurate engineering, and thorough analysis are as follows: The geometric steam boiler's volumetric capacity was determined to be 0.036 m³, and its maximum steam pressure was determined to be 7 bar. Heat transfer from the furnace by conduction and convection were evaluated as 27224K and 66878K, respectively. The geometric boiler efficiency was determined as 79.7%. Also, the MATLAB results indicate that larger boilers can handle higher pressures, larger boilers have improved efficiency, and continuous, prolonged boiler usage results in lower efficiency, while scheduled shutdowns increase it. A positive correlation exists between boiler efficiency and furnace thermal efficiency, with a steep upward trajectory indicating a significant impact on boiler efficiency. Radiation makes the most minor contribution to heat transfer, with convection predominant. Furthermore, the successful operation of the steam boiler underscores the relevance of multidisciplinary collaboration between mechanical engineering, thermodynamics, materials science, and regulatory compliance.
