The discussion about possibility of deployment of MSW incineration boilers to generate electricity in Brazil is the major topic of this paper. In this article are showed some advantages and disadvantages of this technology, as well as a methodology for the estimate of area for the main equipments of a steam generator for a boiler incineration

Auditoria energética em caldeira de monóxido de carbono

Within the concepts of sustainability, energy audit magnified its importance in managing systems in industrial plants. Can reduce waste and save energy representative, the improvement and development of thermal and electrical systems can be very attractive to business. With the focus on a boiler generating steam, the energy audit aimed to increase efficiency and eliminate energy losses of the heat engine. The boiler in question is commonly called CO boiler because most of the calorific power provided comes from this. Using a fuel gas from the catalyst regeneration process, it has featured in the boiler power generation system of the refinery. Burning a mixture of gaseous components from discarded into the atmosphere, the heat engine can generate tons of steam just as the other boilers installed. The challenge was to work with this gas mixture and obtain maximum efficiency, reduce moisture and enjoy the warmth of the heat exchange have been studied and recommended. Every project, from evaluation of the variables in the composition of fuel gas, to the using of heat exchangers and refrigeration system are suitable for evaluation and improvements

Produção de hidrogênio por reforma a vapor de biogás

A new approach to generating clean energy has been studied by several researchers, among which one can highlight the steam reforming of biogas. The Biogas is result of decomposition of organic matter and it hasn’t been availed in the global level, instead, the biogas has been burned in flare or discarded into the atmosphere providing damage to the environment. The generation of vector biogas energy can be realized through its steam reforming and this work examines briefly the types of digesters used for biogas generation, studying the process of steam reforming to generate hydrogen as energy vector, analyzing each step in detail, seeking to adapt its main features an ethanol reformer for a biogas reformer. Besides this it is estimated the yield of the reform process and the boiler efficiency for efficiency of the process

Aspectos técnicos e ambientais da incorporação de novas tecnologias no setor sucroalcooleiro: produção de hidrogênio e gaseificação do bagaço

The purpose of this work is to study the incorporation of hydrogen production (Case A) and the process of gasification of sugarcane bagasse associated with combined cycle gas turbine and steam turbine (Case B) for Distillery Pioneers process. These technologies can be used to improve the energy supply in the sugarcane mill. Initially the processes for obtaining sugar and ethanol from sugarcane is discussed, with a theoretical introduction to hydrogen, the process of steam reforming and gasification of biomass (bagasse) by inserting a turbine associated with the recovery boiler gas. Subsequently makes up the energy and exergy analysis of the incorporation of the above technologies. In end stage makes it an ecological analysis considering or not the carbon cycle (photosynthesis), to determine the levels of emissions of pollutants, carbon dioxide equivalent, indicators of pollution and ecological efficiencies associated with technological developments proposed. It is concluded that hydrogen production by steam reforming of ethanol and gasification of bagasse are viable alternatives from the point of view of technical and environmental applications in the biofuels industry, contributing to the development of the sector in the country
