Item Desenvolvimento de um Modelo Matemático para a Avaliação da Eficiência da Combustão em Usinas Termoelétricas Operando com Gás e Alternando com Diesel(INSTITUTO DE TECNOLOGIA, 2015) AZEVEDO, Manoel S. Santos; LEITE, Jandecy Cabral; CARVAJAL, Tirso Lorenzo Reyes; RODRIGUEZ, Jorge Laureano Moya; RICO, Iván Leandro Rodriguez; DÍAZ, Pablo Romélio Roque; GOMES, Paulo Cezar Rocha.; Prof Dr. Walter Barra JuniorThe article presents a mathematical model developed to evaluate combustion efficiency in thermoelectric power plants operating with natural gas (NG) and alternating with diesel (HFO). The study was conducted in a plant transitioning to dual-fuel use, aiming to optimize energy efficiency and reduce pollutant emissions. The model covers stoichiometric, thermodynamic, and kinetic aspects of combustion, implemented in software for real-time analysis. Results demonstrated the model's feasibility in predicting engine performance and optimizing specific fuel consumption, with practical applications in plant operation.Item An Approach for Life Cycle Assessment of Electricity Generation at Gas-HFO Internal Combustion Engines in a Central Station(Universidad Central “Marta Abreu” de Las Villas, 2014) TOUSET, Juan-Pedro Hernández; LEITE, Jandecy Cabral; RICO, Iván-Leandro Rodríguez; FRANÇA, Alcimar de Jesus; DOMINGUEZ, Elena-Rosa; GUEDES, Oiama de Assis; JIMENEZ, Italo-Jorge Tavares; ARTILES, Arnaldo Herrera; GIL, Maylier Pérez; NASCIMENTO, Manoel Henrique ReisThis paper applies the Life Cycle Assessment (LCA) as an assessment tool to quantify the environmental impacts associated with electricity generation by internal combustion engines. Steps, resources, and/or supplies that have the greatest impacts during the life cycle of electricity generation are identified to contribute with measures of cleaner production in companies with similar power generation. The goal of this study is to evaluate the environmental impacts associated with the production of 1552 kWh of electricity by gas-HFO internal combustion engines, considering a scenario that responds to the use of lubricating oil, oily water treatment, collection, and transportation of sludge. The study of additives and contaminants from lubricating oil is included, taking into account that it is a complex task for life cycle inventory considering limitations to get data.
