Mathematical Simulation of Combustion Process in Top-fired Hot Air Furnace
For a long time,industrial enterprises occupy a pivotal position in global energy consumption.As one of the core equipment of these enterprises,hot blast stove plays an irreplaceable role in industrial production.Hot blast stove is not only the main body of energy consump-tion,but also an indispensable heat provider in the industrial production process.The working principle of hot blast stove is mainly to use the heat generated by fuel combustion,and transfer the heat to the air through the heat exchanger to produce high temperature hot air.These high temperature hot air are widely used in various processes in industrial production,such as drying,sintering,melting,etc.,which plays a vital role in improving production efficiency and product quality.Based on the introduction of the burner structure of the top-burning hot blast stove,it discusses the current situation of numerical simulation of the top-burning hot blast stove,focuses on the analysis of the combustion geometric model and mathematical model of the top-burning hot blast stove,and analyzes the mathematical simulation results from the velocity distribu-tion and temperature field distribution,hoping to improve the combustion efficiency of the hot blast stove by optimizing the combustion process.Reduce fuel consumption and energy costs.
