In this study, the potential of cotton stalks as feedstock for a gasifier is analyzed. The emissions and performance characteristics of the gasifier-engine system is analyzed by running the engine at different loads. These characteristics of the dual fuel diesel engine are compared to those under different load conditions. Specific fuel consumption in the dual fuel mode of operation is favorable at all load conditions. CO emissions are much higher in the case of the dual fuel (diesel + gas) mode of operation as compared to that of diesel-only mode, and the level of NOx emissions is drastically reduced in the case of dual fuel mode.
