Resumo
The thermal energy in the form of heat generally is produced and provided through thermal plants by combustion using coal, a type of fuel which impacts the environment severely. An effective way for reducing the specific consumption of coal is the preheating of the air intake system, which is responsible for increasing the flame temperature, a fundamental parameter in the control reactions that occur internally. The aim of this study is the computational modeling of a cyclonic furnace capable of burning biomass powder, and after its combustion process produces the gas temperature above 1500 ° C, evaluate possible methods to reduce emissions and improves the combustion process. For this, it was used the ANSYS FLUENT software. The mathematical models selected for the simulation were described as well as the boundary conditions. Temperature fields, velocity profiles and species from the exhausted gas were obtained.
