Abstract
In the present work, we performed IR diagnostics in the external flame of a new burner using the example of waste engine oil being sprayed by a high-speed jet of superheated steam. The experiments were carried out in a wide range of operating parameters (steam flow rate and temperature and fuel flow rate). In measurements, we used a FLIR thermal imaging camera of the special JADE J530SB series and platinum-rhodium-platinum-rhodium thermocouple of type B. Instantaneous and average temperature fields are obtained. The influence of device operation parameters on the temperature in the external flame of the burner is established. The maximum temperature reaches 1240°C. With increasing mass concentration of steam, a decrease in temperature is observed. This is due to dilution of a combustible mixture and a decrease in its heat capacity. A decrease in the flame temperature in the presence of steam may indicate a decrease in formation of thermal nitrogen oxides.
