Process optimization and performance evaluation of a downdraft gasifier for energy generation from wood biomass

In recent time, due to the increasing demand for energy and the need to address environment-related issues, a great deal of focus has been given to alternative sources of energy, which are green, sustainable and safe. This work considers the process optimization and performance evaluation of a downd...
