Análise do consumo de biomassa em um gerador de vapor de uma unidade de beneficiamento de sementes de milho

Abstract

This work aims to make an analysis of the volume of biomass produced and consumed in a mixed boiler for the steam generation process, which will be used in the drying process of ears in a maize seed processing unit installed in the city of Uberlândia , Minas Gerais. One of the main steps in the process of seed processing is drying. This step has several advantages and, when done correctly, considerably prolongs the useful life of the final product. One way of performing drying is by heating the air which will pass through the mass of spigots into the drying chamber. To heat the air, you can use water vapor generated in a boiler. The beneficiation unit studied produces a large amount of biomass throughout the process steps. The biomass consists of corn and cob straw. Currently the company uses about 14 ton/h of biomass during the harvest period to feed a boiler which generates steam to heat the air that will be used in the drying process of the grains. The present study analyzes the current scenario of the company in relation to the topics mentioned in this summary and proposes the implementation of a turbine for the generation of electric power fed by the surplus of steam produced in the boiler.
