Uso de uma caldeira a biomassa para análise e propostas de soluções para melhoria na eficiência

Abstract

This study addresses the production of renewable and clean energy, with a focus on the use of biomass as a source of energy in boilers. Among the available technologies, biomass boilers have stood out as one of the most viable options, but it is necessary to control the emission of polluting gases. For a comprehensive analysis of the performance of biomass boilers, it is essential to consider various aspects that can influence their operation and environmental impact. In this context, the objective of the study is to identify and propose solutions to the problems encountered in the biomass combustion system in a boiler, such as low steam consumption, duct overheating, and formation of silica stones. The study was conducted on a biomass boiler with a capacity of 10 to 15 tons/h of saturated steam, with a working pressure of 10 kgf/cm², using wood chips and sugarcane bagasse as energy sources. The fuel transport system was also analyzed and divided into storage and feeding systems. The study aimed to identify and propose solutions to the problems encountered in the biomass combustion system, as well as evaluate and properly plan the burning efficiency and improve the fuel transport system. It is concluded that preventive measures such as routine inspections and more frequent cleaning are necessary, in addition to the need for corrective interventions.
