Stirling engine operating with solid waste in rural area

The use of syngas derived from biomass gasification as fuel for internal combustion engines presents significant challenges due to the presence of harmful impurities. However, syngas combustion offers an effective heat supply solution for external combustion engines, such as Stirling engines. This report details the design, fabrication, and testing of a gasifier-stirling engine system using rice husk-derived RDF as fuel. Rice husks are compressed into honeycomb-shaped pellets to improve biomass storage and enhance gasification efficiency. The Stirling engine can be heated directly by the combustion of RDF pellets or indirectly by syngas produced through the gasification of RDF in the gasifier. Initial results indicate that the difference between the simulated and experimental combustion temperatures of RDF is approximately 13%. The gasifier-Stirling engine system has been fully designed and manufactured, ready for testing in the next phase of experimentation.
