Estudo e avaliação de um sistema de micro cogeração com motor de combustão interna usando gás natural

Abstract

With the country economic growth recent years and present prospects of further growth, government, entrepreneurs and researchers, concerned about possible "weakness of the energy sector, " already put in evidence during the years 2000 and 2001, when the country suffered its first crisis, seeking to develop new technologies that allow "give off" in conventional electric and thermal energy systems, providing new energy of source. The time of peak demand, environmental impacts and energy efficiency are factors to be considered in these new technologies. In this context, cogeneration is the work being developed in the evaluation of new systems for power generation in the country, offering greater long-term demand, with quality and efficiency in energy consumption. Cogeneration based on reciprocating engines to natural gas has less polluting energy sources with reduced cost compared to conventional fuels (diesel, kerosene). The unit power generation facilities will meet the physical understood by the Energy and Environment Control Instrumentation Laboratory, Mechanical Shop of LES and the space of the Energy Sustainable Institute, placed in RECOAS bulding Co-Generation Room Machines, combustion and Engines Laboratory and Engines. Specifically the study will be adapted and applied the cases of energy assessment as the result of the Sankey diagram, allowing check the whole energy process.
