Temperature Field Simulation of Asphalt Heating Furnace

Abstract

For the problem of low heating efficiency of asphalt heating furnace, a simulation model of temperature field of asphalt heating furnace was established. By simulating the process of gas flow, the temperature field and temperature flow line diagram of the gas in the asphalt heating furnace are obtained. In order to improve the heating efficiency of the asphalt heating furnace, the model is structurally optimized. Analyze the effect of different positions of the gas inlet of the asphalt heating furnace, on the gas temperature; observe the effect of the added deflector in the lower furnace chamber on the gas flow direction. The results show that the temperature inside the furnace chamber is higher with the same gas inlet, and the addition of the deflector in the lower chamber can further improve the heating effect of the high temperature gas on the bitumen inside the furnace.
