Furnaces serve as essential equipment in industrial processes for transferring heat to solid or fluid masses to induce physical or chemical changes. This document provides a comprehensive overview of fired heaters, categorized as combustion furnaces that generate heat through fuel combustion for direct or indirect heat transfer to materials. Tubular fired heaters, crucial in the oil and chemical processing industries, are designed with radiant and convection sections for efficient operation. The document discusses the thermal efficiency of these systems, guided by the Stefan-Boltzmann law for radiative heat transfer, while also addressing practical complexities such as the impact of furnace geometry on heat exchange factors. Additionally, it highlights the critical sources of heat input within the radiant section, including combustion heat and sensible heat from combustion air. A systematic approach to calculating flue gas temperatures via heat balance equations is introduced, emphasizing the significance of minimizing thermal losses through proper furnace design. The discussion encapsulates fundamental principles applicable to the design and optimization of fired heaters in petroleum refineries and other chemical process industries.
