摘要：

The effect of superheated water vapor on the flame characteristics was experimentally studied by IR thermography in a wide range of operating parameters using a spray burner and diesel fuel. A FLIR thermal imaging camera (JADE J530SB) was used for measurements. The instantaneous and average temperature fields were obtained and time-averaged temperature profiles were constructed along the symmetry axis of flame. The maximum flame temperature as a function of steam consumption at constant fuel consumption was found: with increasing steam consumption, a decrease in temperature is observed, which can positively affect the concentration of hazardous substances in exhaust gases. It was also found that with an increase in fuel consumption at constant steam consumption, the maximum flame temperature shifts from the base of the flame, and the high-temperature flame zone increases. The obtained data can be used for numerical simulation of combustion.
