Numerical simulation of temperature field in high temperature regenerative heating furnace was studied by using Fluent software.The gas parameters influencing temperature field

flow field and concentration field in furnace were mainly analyzed.The research results are as follows: the relative speed of the air flow plays a vital role in temperature distribution;the lower the relative speed of jet flow between the natural gas and the air

the wider the high temperature zone is;moreover

the higher the average temperature in the furnace is

the better the homogeneity of average temperature is;when the air preheating temperature is constant

to improve the preheating temperature of nature gas

the maximum temperature in the furnace also can enhance along with it;when the temperature of air is lower

the concentration of NO increases exponentially with the air preheating temperature increased;however

when the temperature of the air is higher

the concentration of NO decreases exponentially with the air preheating temperature increased.
