Abstract

The infrared asphalt heater uses a gas fuel source to heat the ceramic plate, then radiates the heat to the pavement to soften the asphalt layer for the pavement repair process. However, in order to improve the efficiency of the flame in the combustion chamber and avoid the flame burning directly on the road surface, it is necessary to study the characteristic parameters of the flame in accordance with the structure of the combustion chamber of the machine. The article presents two problems: firstly, research on the characteristics of the gas flame in the combustion chamber to determine the relationship between flame length and temperature; secondly, calculation of the pressure loss during fuel combustion to determine the actual pressure of the combustible gas mixture in the combustion chamber of the pavement heater. This is the scientific basis for determining the parameters to design the fuel burner of the infrared asphalt heater.
