OSIRIS, C. (2011). Study of heat transfer in the flame tube furnace using beef tallow. 63p. Tese (Doutorado) – Escola de Engenharia de São Carlos, Universidade de São Paulo, São Carlos, 2011. In this study, we evaluated the burning of tallow by a calorimetric flamotubular instrumented furnace which operates at atmospheric pressure. As part of the experimental work, the curves of thermal efficiency of fuel combustion (beef tallow) were analyzed, and it was possible to set their composition toward the transfer of heat and gas emissions. Experimentally, the calorimetric furnace was remodeled and adapted to operate with beef tallow by incorporating an element of this preheating, it is a burner developed in NETeF and it has a system to supply heating for fuel, as the tallow is solid at room temperature.The burner used in the experiment was of mixed type. The results of measurements of the calorific value of beef tallow were shown to be high: 39985.5 kJ / kg (data obtained in the laboratory of NETeF), causing the fat to become a viable source.
