Design and construction of a carbonization waste heat recovery for briquette drying

Abstract

This project explores the potential of utilizing waste heat from the carbonization process to improve biomass briquette drying, a process currently reliant on weather-dependent sun drying and biomass combustion in Uganda. The primary goal is to design and construct a waste heat recovery system that captures heat from flue gas and applies it to briquette drying, thereby reducing drying times. The project's outcomes include a comprehensive final design with technical specifications (drawings, fabrication steps, bill of materials, and power needs), as well as a demonstration of a drying system powered by recovered flue gas heat. This document provides a foundation for future advancements in carbonization waste heat recovery for briquette drying. The report also presents a technical evaluation of the developed system's performance, specifically examining the moisture removed from briquettes of 12% for 12 hours of operating the system.
