Burner position in cement kiln

Aug 31, 2021

approach to cement kiln burners focuses greatly on scale modelling and CFD simulation. The Turbujet™ is a high momentum kiln burner that provides a very firm and steady flame that can be designed to fit every kiln situation. Primary air slots provide effective jets that result in better mixing of the secondary air into the flame

    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
