Design and Testing of Plastic Waste Torrefaction Reactor for Improved Torr Gas Production

Abstract

The growing demand for sustainable and renewable energy sources has sparked research into biomass torrefaction as a potential alternative to fossil fuels. This paper discusses the design and construction of a compact torrefaction biomass reactor, which uses charcoal as the primary heat source. The reactor system comprises a jacket, flange, convergence cone, charcoal tray, condensing and gas extraction unit, blower, and angular steel frame. The reactor, made of 3mm-thick mild steel, features a blower-driven hot air circulation system for efficient biomass torrefaction due to its durability and heat resistance. The condensing unit was equipped with a continuous water circulation system for efficient cooling and gas condensation. The experimental phase involves biomass preparation, size standardization, temperature management, moisture extraction, energy density, product properties, and comparison with traditional fossil fuels. Torrefied biomass improves fuel quality and energy density by 30-40%, reducing moisture and volatile matter, and offers faster burning rates, efficient energy release, and cleaner combustion.
