Buoyancy of your flame can generally be counteracted by a slight downward tilt of the main air pipe so the main entire body in the flame might be centered at a particular length In the burning zone. In Fig. six.2, flame E exhibits a buoyant flame with the main air pipe centered within the kiln axis. By tilting the pipe down marginally, the flame assumes the situation demonstrated by flame F.
