title: System characteristics and performance evaluation of a trailer-scale downdraft gasifier with different feedstock.
abstract: The main objective of this study is to investigate the thermal profiles of a trailer-scale gasifier in different zones during the course of gasification and also to elaborate on the design, characteristics and performance of the gasification system using different biomass feedstock. The purpose is to emphasize on the effectiveness of distributed power generation systems and demonstrate the feasibility of such gasification systems in real world scenarios, where the lingo-cellulosic biomass resources are widely available and distributed across the board. Experimental data on the thermal profiles with respect to five different zones in the gasifier and a comprehensive thermal-chemical equilibrium model to predict the syngas composition are presented in detail. Four different feedstock-pine wood, horse manure, red oak, and cardboard were evaluated. The effects of C, H, O content variations in the feedstock on the thermal profiles, and the efficiency and viability of the trailer-scale gasifier are also discussed.
