Abstract

In order to study the gas movement in oxy-fuel combustion heating furnace, the fire simulation software FDS (Fire Dynamics Simulator) is used to build the simplified model of oxy-fuel combustion heating furnace and carry on the correlation analysis of simulation parameters and mesh number which impact the calculation accuracy. Based on the above correlation analysis, the numerical calculation of the gas movement in the cold state oxy-fuel combustion heating furnace at different nozzle speeds is carried out, and the calculated results are compared with the experimental results measured by the hot wire anemometer to verify the correctness of the simulation. The results suggest that the maximum reflux region increases with the increase of the air velocity and has a certain time delay under the condition of experiment speed, which provides a reference for the ignition delay of the thermal state oxy-fuel combustion heating furnace.
