A Prototype Downdraft Gasifier Design with Mechanical Stirrer for Rice Straw Gasification and Comparative Performance Evaluation for Two Different Airflow Paths

Journal of Agricultural Sciences, 2018
In this research, a prototype downdraft throatless gasifier was designed with a mechanical stirrer. The gasifier was designed for gasification of rice straw pellets. The diameter of the reactor was 350 mm and a nominal value for the heat power of biomass

Hybrid Biomass and Natural Gas Combined Cycles: Performance and Economic Analysis

IET Renewable Power Generation, Volume 19, Issue 1, January/December 2025.
The performance of a cogeneration system is explored in this study by analyzing the impact of natural gas fuel and synthesis gas from renewable biomass sources. The hybrid drive in the system utilizes both a gas‐burning internal combustion engine and an external combustion engine (Sterling type alpha engine).

Optimized Co‐Gasification of Industrial Sludge and Waste Wood Pellets Using Reduced Slag as Bed Material in a Fluidized Bed Reactor

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
This study presented an innovative co‐gasification approach using industrial sludge (IS) and waste wood pellets (WP)—two common industrial wastes—within a bubbling fluidized bed reactor. Additionally, reduced slag, a Ca‐ and Mg‐rich byproduct of blast furnace operations, was used as the bed material, effectively preventing bed agglomeration commonly ...
