Cogeração de energia com motores de combustão interna

The tertiary sector is largely responsible for the growth of electricity consumption in Brazil. The large commercial and public buildings, hypermarkets and shopping centers stand out as major consumers of electricity for lighting, power and thermal energy. Brazil presents significant potential for the deployment of small cogeneration plants, especially in the tertiary sector. Allied to this, the possibility of natural gas supply and the growing demands in favor of maintaining and preserving the environment favor the implementation of cogeneration plants. In this context, this paper presents a technical and economic analysis of installing a cogeneration plant using internal combustion engine with natural gas in a mall

Estudo sobre fornos de tratamento térmico e propostas de cogeração de energia em usina siderurgica não integrada

Steel industry is a sector heavily dependent on energy, both electrical and thermal. Since the receipt of raw materials to the shipment of finished products to customers, through mergers, casting, rolling, heat treatment, inspection, among others, high amounts of energy are demanded, generating very significant costs to the productive chain in its entirety . Therefore, any alternative that favors the reduction in energy consumption or barateie the cost of this is very welcome. Within this context, this paper aims to make a technical and economic analysis of installing a cogeneration plant in the field rolling in a non-integrated steel mill. Two configurations are proposed plants, with one being the use of heat from waste gases from furnaces existing in the area mentioned and another with the use of heat from waste gases from an internal combustion engine. Both proposals are evaluated technically and later is done the economic analysis, calculating the financial return (pay back) in relation to the investment required, operation and maintenance of the plant

Estimativa do potencial de acréscimo da oferta de energia no setor sucroalcooleiro paulista a partir de cogeração e gaseificação do bagaço de cana-de-açúcar com utilização de ciclo combinado

This work evaluates the existing potential in the state of Sao Paulo for the generation of electrical energy using the sugar cane bagasse as fuel. As the bagasse is a by-product of the sugarcane and alcohol industry and it is produced in large scale in the country, mainly in the state of Sao Paulo, it is important to develop researches that aim the best utilization of this input. In order to determine its potential, at first, a study was conducted considering the utilization of the cogeneration, which is a common practice in the plants of the sector. However, it was concluded that the cogeneration could provide a higher quantity of energy if more modern technologies and more efficient processes were used. Another study to estimate the potential considered a system of gasification of the sugar cane bagasse integrated with the combined cycle (BIG/GTCC). It was concluded that this technology can provide a considerable increase in the electrical supply. In this work it was also developed an energetic study based on real data from a plant located in the state of Sao Paulo. A thermodynamic analysis was done in the existing equipment of the cogeneration section of the plant. And another analysis was done considering the implementation of the BIG/GTCC technology to the cogeneration system. Comparing the results of both settings, it was concluded that the utilization of the sugar cane bagasse integrated to a combined cycle increased considerably the efficiency in the generation of electricity of the plant, increasing more than six times its production capacity of electrical energy
