What Factors Can Influence Rotary Kiln Burner Working

Nozzle position when the secondary air enters the rotary kiln burner the mixing of the primary and secondary air is weak which extends the burning time and makes the flame extend for example before the secondary air enters the kiln the mixing between the primary and secondary air will be strengthened to shorten the flame
