Design of burner performance optimization system based on laser machining

Abstract

The existing burner performance optimization system neglects the measurement of single pulverized coal particle temperature in the combustion process, so the temperature control error is large, which leads to poor performance improvement of burner and poor control of residual oxygen. Therefore, a burner performance optimization system based on laser machining is designed. Design the overall frame of burner performance optimization. The performance optimization of the burner is mainly realized by the control of temperature and oxygen content. The gas quantity is calculated and fed back to the PID controller through the error value and the rate of temperature difference between the actual temperature and the set temperature. Based on the Hencken plane flame burner, an optical measur?ing system for single pulverized coal particle ignition based on laser processing is established to obtain the temperature of the particles. Based on this, the Proteus-based burner transient temperature distribution subsystem and the steady-state ANN model-based temperature control optimization algorithm are designed. The experimental results show that the burner of the system can control the residual oxygen very well, and the temperature control result of the system is highly fit with the simulation result, so the temperature control precision of the system is high.
