Aumento de geração de vapor em uma caldeira de biomassa: estudo em função da estabilidade operacional

Abstract

With industrial development and concern for the environment, there is a demand for alternative, renewable and low-cost fuels, following a growing trend around the world, ie the use of this forest biomass (bark, chips and forest residues) has gained prominence in the energy scenario for the production of steam and electricity generation and Brazil is a privileged country because it has large renewable energy resources in relation to other countries. This work aims to develop a study on the possible causes, difficulties, characteristics, qualities, problems and differences in the conditions of the solid fuel system of a high pressure biomass boiler with bubbling fluid bed (BFB), both in the systems transport, distribution and feeding of this biomass to the boiler, focusing mainly on the biomass from the logging process, the forest residue chip and the sawmill chip when necessary in a pulp industry.
