Abstract

This research will study the three-dimensional behavior of bagasse combustion within the combustion chamber of a production module of organic sugar, with the aim of improve the combustion efficiency, reduce production costs and ensure its energy selfsufficiency. The procedure consisted, firstly, of a simulation of the combustion of bed of solid fuel, bagasse, on a grate, with a mathematical model implemented in MATLAB® giving as a result the composition of a gaseous fuel. Secondly, the combustion of the resulting gaseous fuel was simulated with the commercial software ANSYS FLUENT® using the geometry of the combustion chamber of a production module of organic sugar located in the highlands of PiuraPeru. Three cases of primary-secondary air ratio were studied: 70-30%, 60-40% and 50-50% as well as the effect of the addition of secondary air in two ways: through tubes and, the second way, through tubes plus through the door for feeding bagasse. From the results, it is concluded that the greatest average temperature of the combustion products at the outlet of the chamber is obtained by the addition of secondary air by tubes in a proportion of 50% of total air admitted; temperatures higher than 1500 K are reached.
