WebMar 29, 2024 · Now, the flame is of the colour of yellow. This colour is because of its temperature. This is to produce enough soot to be luminous. Now the flame is operated at a lower temperature than its efficient heating flame (see Bunsen burner). The given colour of simple incandescence is due to black-body radiation and the frequency of the flame. Webflames with high emissivity is lower thermal NOx emissions. To demonstrate this, consider a flame in a rotary kiln heating clinker to 1450°C.
