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.Item Melhoria do Desempenho de Motores de Combustão Interna em Empresa de Geração de Energia - Via Implantação de Manutenção Preditiva(Universidade Federal do Pará, 2011) FONSECA JUNIOR, Milton; BLANCO, Claudio José Cavalcante, Ph.D.This work aims to describe the main issues related to implementation of TPM (Total Productive Maintenance) and PM (predictive maintenance) in power plants using internal combustion engines. The two types of planning were presented with emphasis on maintenance activities. Currently the generation planning of the company do not allow unplanned outage. The most common faults were as a result of unbalance, misalignment, improper setting, coupling defective and contaminated oil. Issues that were eliminated with the implementation of predictive maintenance and implementation of a TPM program. Emphasis was placed on the importance of four pillars in this methodology (specific improvements, Autonomous Maintenance, Planned Maintenance and Education & Training). By the use of this methodology, it was shown some results achieved after its implementation such as: reducing the annual cost of maintenance, reduction of corrective maintenance, increase of MTBF (Medium Time Between Failures) and reduction of MTTR (Mean Time To Repair) in all areas of our plant. These results are reflected in the power generation and more reliability for our customers.
