Influence of Air Flow Velocity on the Combustion Process in Combustion Chambers of Radiant Heaters

Statement of the problem. The issue of automation and optimization of air supply regulation in radiant heater combustion systems is being investigated. The aim of the work is to develop an algorithm for regulating the air flow to increase energy efficiency, improve the stability of the combustion process and reduce emissions of harmful substances. The main objectives of the study are to develop a flowchart for controlling the air supply in burners and a description of all key control stages, as well as to analyze the mathematical dependencies describing the combustion process, including calculations of thermal efficiency and flame temperature. Results. During the work, a block diagram of the process of regulating the air flow in the burners of radiant heaters was developed. The analysis of the key stages of air supply control has been carried out and their impact on gorenje efficiency has been assessed. A mathematical model of the combustion process is constructed, describing the dependence of thermal efficiency on the air supply rate and the excess oxygen coefficient. Conclusions. The study showed that automation of the airflow control process contributes to improving the energy efficiency of systems by maintaining optimal combustion conditions. It has been found that the turbulence of the air flow improves the mixing of fuel with air, which leads to complete combustion and a reduction in emissions of pollutants. However, excessive turbulence can reduce the flame temperature and increase heat loss.
