Utilização do cavaco de madeira como combustível alternativo para a produção de vapor de água em uma caldeira aquatubular com grelha fixa do tipo PIN HOLE

The steady increase in the price of oil and its derivatives, carbon credits, the concern with the environment combined with the precipitation of rain water and lack of water resources that Brazil has suffered in 2014 caused a migration of participation sources of energy in the Brazilian energy matrix. The hydropower sector suffered big drop at 2013 and is suffering so far, contributing thus to the generation and cogeneration of thermal energy using renewable energy sources such as: sugarcane bagasse, wood chips, rice husks, among others. The selling price of the electricity market reached the level of R$ 807, 00 MWh in January 2014 (Source: ANEEL), heating the Brazilian thermoelectric sector. Although thermoelectric use in bulk water as vaporizing fluid to produce electricity and use in various processes, water reuse plans have become an important factor in these industries. The increased use of biomass has been the bagasse which is allied to the sugarcane sector, strong market in Brazil, and consists basically use the rest of sugar cane, sugarcane industries that would play out. The sugar and ethanol industry is very unstable and only lasts for 6-8 months a year, and the remaining time in the period known as between crop that corresponds to the planting and harvesting of sugarcane and then enter the period of vintage which is the constant cane harvesting and crushing it. This instability of the market and the thermoelectric idle period leads the thermoelectric industries to seek other sources of renewable energy, such as wood chips (pine, Eucalyptus, Orange), rice husk, sorghum among others, to not be dependent on alcohol sector. The present work aims to study the use of wood chips as an alternative biomass for burning a fuel that essentially uses bagasse, the thermoelectric in question consists of two boilers that produce together 350 t / h ...

Os impactos da escravidão moderna na Região Amazônica Brasileira em relação à economia, à sociedade e aos direitos humanos, com ênfase na atividade econômica pecuária (2003-2010)

Este trabalho visa definir o conceito de escravidão moderna como as condições análogas ao trabalho escravo e como este afeta a vida de milhares de cidadãos brasileiros na vasta região amazônica. Serão apresentados dados de organizações mundiais sobre o trabalho escravo moderno, estudos brasileiros que corroboram a argumentação de que existem milhares de pessoas na Amazônia que são escravizadas e que estão em condições degradantes de vida nas mais diversas atividades econômicas. Focar-se-á na atividade de criação bovina, pois, além de ser muito difícil analisar todas as atividades econômicas com a devida importância que cada uma merece, a atividade em estudo é a que mais emprega mão-de-obra escrava atualmente na região Amazônica

Pontes de madeira para pequenos vãos para situações emergenciais

In Brazil there are many cases of cities that suffer from flooding. It often destroys much of the structure of the city, and isolates many families. Relying on emergency measures for these cases and similar cases is of utmost importance. This paper proposes the development of a project of a timber bridge that can be used in emergency situations such as occurs in situations of floods and especially on side roads. It is considered one type of structural bridge which has, among other characteristics, an easy transportation and assembly of the elements. The development is carried out, at this early stage of the project, only about the verification and sizing of structural elements of the superstructure of the bridge. For this purpose, it relies on computer programs, and fundamentally on PCFrame Visual Taco. The first allows you to model the structure and determine the efforts of calculating the elements, and the second one assists at the scaling and the verifications in accordance with the Brazilian technical standards for timber bridges. The wood used in the project comes from the tree Eucalyptus saligna, which is easy to acquaint and manipulate and comes from the region Vale do Paraíba. The bridge in this case of application should have the characteristics mentioned below: short execution time, simplicity of structure and an assembly of a relatively low cost
