Numerical Study of A Modified Shuttle Kiln with a Novel Combustion System
By modifying the combustion system of the shuttle kiln,an improved structure for a shuttle kiln was proposed,with the combustion system of the improved shuttle kiln arranged on both sides of the kiln.Numerical simulations were conducted by modeling both the improved shuttle kiln and the traditional one,combined with a combustion model.A comparative analysis of the internal temperature,velocity,and CO distribution inside the two kilns was performed.The results indicate that the traditional shuttle kiln forms a high-temperature region at the top due to flame influence,resulting in a significant temperature gradient between the top and bottom of the kiln.In contrast,the modified shuttle kiln shows no localized high-temperature region at the top,which significantly reduces the temperature gradient inside the kiln.The uniformity of internal temperature and the reducing atmosphere in the modified shuttle kiln are superior to those in the traditional shuttle kiln.This improvement is more favorable for product firing and provides a theoretical foundation for the structural improvement of shuttle kilns.
