This study aims to show the methodology and results related to the calculation of fluidization velocities in a bubbling fluidized bed gasifier. The pressure drops encountered by a fluidizing agent in the particle bed are also exposed. Velocity calculation is important because it enables a good fluidization, which induces a uniform distribution of particles. The good distribution of particles causes a uniform distribution of temperatures in the gasifier where the thermochemical reactions of the process are performed. Biomass functions as a reactor fuel, and accurate fluidization provides a summarized way for correct gasification. Good calculation of pressure drop in the bed is vital for the correctly selecting a blower, a device responsible for providing the power and airflow necessary for fluidization. The bed particles are bauxite with 86% alumina with a density of 2960 kg/m3 and an ave...

The scope of this paper is to make a feasibility analysis for energy production from sugarcane byproducts in Perú. Therefore, it is shown the history, methods, current scenario and future prospects of sugarcane plantations related to the ethanol industry and the sugar industry. There will be shown analysis of harvest residues (top and leaves). Bagasse is a mill residue, produced after sugarcane juice is extracted from the sugarcane. Nowadays this residue is burnt in boilers and this energy is used to generate steam. In the other hand, harvest residues represent a significant part of the energy contained in the sugarcane, but it is left in the field, or worse; burnt before the harvest. There will also be shown an estimated value of the electricity generation potential from sugarcane residues.
