To estimate the noise emitted by a industrial tube burners (immersion tube burner and radiant tube burner), simulated and experimental analyses are carried out. Firstly, combustion noise is measured and the overall characteristic of noise is examined. Secondly, one-dimensional noise analysis programmed with a transfer matrix method is used. A lot of efforts have been made to analyze the noise from home use combustion device considering the temperature distribution inside the tube. In this study, the distribution of heat generation rate is taken into account to obtain sufficient accuracy for the noise at the exhaust tube outlet, in addition to the conventional temperature distribution. The distribution of heat generation rate is numerically analyzed considering the heat transfer at the inner and outer surface and the radiation at the outer surface of combustion tube. As a result, the theoretical results show relatively good agreement with the experimental results and the analytical method employed in this study has been confirmed to be practical for noise analysis of industrial tube burners.
