Flame path alterations is usually because of uncommon working problems. If an endeavor had been produced to regulate the flame route at these types of moments, there will most probably be an unwanted flame as soon as the kiln returns to standard running problems once more.
On some rotary kilns, the first air pipe is set a little down below the middle of the kiln, in an effort to offset the flame buoyancy. Most kilns, having said that, have amenities for modifying the placement of the principal air pipe plus the burners, Consequently the operator can transform flame course and, to the restricted degree, change the form on the flame.
