During lime production, burner pipes are used to convey and introduce fuels into the pyroprocess. Fuel is conveyed through the inside of the burner pipe pneumatically and blown in to the kiln, where it ignites, providing the necessary heat for the process.

The process environment is subject to thermal shock (the result of a sudden loss of flame), alkali attack (alkali from the fuels), and severe abrasion (from dust-laden air entering the kiln from the cooler). Burner pipes are typically “zoned” with a higher-quality material at the flame end, and the balance of the burner body has a standard low-cement castable. HarbisonWalker International offers ULTRA-GREEN® SR and THOR® AZS for burner tips. Both products provide outstanding thermal-shock resistance along with superior abrasion and chemical-attack resistance. For the burner body, where wear mechanisms aren’t as severe, HWI offers NARCON® 65 CASTABLE, which provides great thermal-shock and abrasion resistance.
