Numerical Simulation and Optimization Design of the Energy-Saving Regenerative Burner

To study the best mixing locations of the gas and the air in such a narrow space within the width of the rotary furnace, this dissertation designs four programs to simulate the regenerative combustion process. By analyzing the simulation results of those four programs, it is found that the furnace reaches the best efficiency if the mixing point locates at 40% to 50% of the furnace-wide. Experimental test also proves this finding, and the results show that when the mixing location is at 40% to 50% of the furnace-width, the flame is stabilized, the temperature reaches uniform inside the furnace, and the extinction by the flame of the opposite burner is also successfully avoided. Therefore, the best mixing location of the gas and the air while regenerative combustion technology is used in the narrow width of the rotary furnace is at 40% to 50% of the furnace-width.
