“…The saturation temperature of the partial pressure of the water vapour is then calculated, which is the dew point temperature of the products. To apply the first law of thermodynamics to combustion processes, the combustion chamber is considered a stationary flow system, which is a function of the enthalpy of each component of the reaction, which is calculated using equation (6).…”

“…In order to increase the efficiency of a boiler through proper control of the combustion process, an optimization software was developed, integrated with the distributed control system and the temperature profile measurement system in the furnace [5]. Similarly, software has been developed for the calculation and optimization of diesel operating processes and fuel injection [6], which have been complemented by the development of multiple numerical models for the simulation of different hydrogen combustion applications, synthesis of sustainable processes, process of combustion of chemical loops in fluidized bed with iron-based oxygen carrier, process of combustion of a pellet fall boiler, pyridine combustion, among others [7,8], however, these software are focused on research and lack a pedagogical component. Therefore, the main contribution of this work is to present the software CombustionUA v1.0, as a user-friendly graphic interface focused on the learning of combustion processes for undergraduate engineering students, allowing them to analyze important parameters such as dew point temperature, air fuel ratio [9,10], adiabatic flame temperature, heat transfer, and excess air.…”

This article presents the use of a graphical user interface in MATLAB® language called CombustionUA v1.0, for the thermodynamic study of the behavior of excess air, relative humidity, and air temperature in complete and incomplete combustion processes. The tool developed allows comparing the performance of different fuels under different operating conditions, since stoichiometry of different combustion reactions, calculation of thermochemical properties of fuels and energy balances have been programmed, so that the user can develop parametric case studies. The work shows the methodology and results of the application of three case studies, which were analyzed using the new educational software. In addition, the fundamental equations used in the development of the software algorithm are presented, as well as the maximum error rates obtained when validating the software in a group of mechanical engineering students at the Universidad del Atlántico. With the help of the software, it was concluded that the fuels with the best air fuel ratio and the highest heat transfer were determined, as well as the differences between the dew point temperatures of a complete combustion and an incomplete combustion.
