five%. This ?�floating??control of the oxygen leads to adjustments of the overall flame size. Experience has shown which the flame size improvements are of minimal magnitude once the oxygen degree is controlled inside this range, and far more Rewards might be derived in working steadiness than in the event the oxygen can be strictly controlled at a constant amount.

Buoyancy with the flame can ordinarily be counteracted by a slight downward tilt of the first air pipe so the main body of your flame will be centered at a specific distance inside 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 somewhat, the flame assumes the posture proven by flame F.
