Buoyancy in the flame can typically be counteracted by a slight downward tilt of the principal air pipe so the primary system in the flame will likely be centered at a certain length inside the burning zone. In Fig. six.2, flame E demonstrates a buoyant flame with the key air pipe centered while in the kiln axis. By tilting the pipe down marginally, the flame assumes the position demonstrated by flame File.
Fineness with the coal has to be these that every one coal particles are burned absolutely when They are really in suspension in the kiln atmosphere. Exactly the same retains legitimate for gasoline oil firing;oil droplets need to be small enough so they melt away absolutely in the exact same method.
