Amongst the most important matters for your kiln operator to recollect is The truth that The trail of your flame just isn't a straight line, and it doesn't keep on being regular at all times. Thus, when the first air pipe is set for your gas-Principal air mixture to vacation toward a certain concentrate on from the burning zone, this will not ensure the flame by itself will stick to this particular path for its full size. The flame tends to raise upward toward the top in the kiln arch, because of the buoyancy ensuing from uneven entrance of secondary air in the kiln.
