Abstract

The objective of this work is to develop a solid fuel with the ability to burn satisfactorily and, to designate a new destination, for the effluent the residual oil of fried foods and sugar cane bagasse. The residual frying oil the frying process can be defined as the heating of the oil at high temperatures (160 – 220 ̊ C) in the presence of air, is an effluent that is largely discarded in the drains which consequently follows to the sewers in this way And can further hinder the treatment of the same. Oils and fats are insoluble or poorly soluble substances in water (hydrophobic), formed by the esterification reaction between glycerol and fatty acids, called triglyceride. The bagasse is a solid residue obtained from the process of extracting sugarcane juice, where it generates a large quantity that is reused to feed the boilers of the plant, to the cogenerations of energies, animal feed and recently to obtain the ethanol Second generation, the latter being technological improvement, is the second in the largest amount of residue in the sugarcane sector, losing only to the Vinasse, for each tonne of crushed sugarcane generates 300 kg environment. Thus, it was developed of experimental and innovative character, a solid fuel that in its composition is contained ethanol hydrated fuel, residual oil, sugar cane bagasse and finally the sodium hydroxide, where it will result in a product with the Combustion capacity, with no risk of explosion, and that it burns securely. Some tests were performed using different proportions in ethanol, sugarcane bagasse and residual oil were tested, with the purpose of obtaining a product with maximum durability, allied to its longest burning time. The durability of the product was evaluated as a function of its storage time, and no packaging type was used. At the end of this work, we managed to obtain an optimized production process, low cost, whose final product is a flame igniter, which can be produced in several geometric shapes, with a slow and homogeneous burning and a very long lasting flame and Stable, which can be used for the firing of barbeciers, fireplaces, campfires and etc. The duration of the flame reached the maximum time of 15 minutes.
