Abstract: Quench chamber is the most important component in the coal gasifier,and is easy to break.In order to find the pattern of turbulent flow and heat transfer of synthetic gas in the Vertical downward pipe,a numerical model based on analyzing the flow and heat transfer features of the vertical pipe in quench chamber is first presented.The variations of temperature,velocity of synthetic gas with the change in length and radius of the vertical pipe and the velocity of the gas are obtained,and the effect of radiation is found. The pattern of turbulent flow and heat transfer of synthetic gas in the vertical pipe is further revealed.
