Projeto preliminar de cogeração aplicado a um forno de produção de vidro plano

The objective of this paper is to realize the preliminary cogeneration project, to be applied on the output of a float glass furnace, aiming the energetic use of the furnace's by-products in other relevant applications on the site. It was analyzed the main points where the cycle could be installed and also the available technologies to energy recovery. After, it was chosen the installation point and the technology to be projected, evaluated the electric power generated and the cycle efficiency. Finally it was evaluated economical indicators in order to verify the project's economical feasibility

Projeto de trocador de calor para uma máquina de aquecimento de vidro para laminação

The object of this study is a glass heating machine for rolling process, designed in 2006 and which is manufactured regularly. By customer request it is intended to increase the production capacity of this machine. However, initial tests have shown that the existing heat exchanger cannot supply the necessary thermal energy demand. A study of the thermal characteristics of the equipment was performed in order to obtain the required information to study alternatives for expanding its capacity taking into account space limitations and the need to rationalize costs, avoiding unnecessary oversizing

Aplicação da fibra óptica em sistemas FTTX

The evolution in telecommunications with the extensive use of optical fiber following the technological expansion and data transmission demand becomes a necessity today. In this paper a literature review with technical concepts, feasibility of projects and applications in data collection with comparisons and highlights of the current situation of this advance is presented. The benefits of using optical fiber and the advantages of FTTH architecture are identified, as well as concrete and devised projects that make this theme reality and future prospects in the continuity of speed increase and allowed broadcasts growth
