Abstract
Service conditions of the refractory lining of the furnaces of drying drums fired by wood fuel (polishing dust for wood fiber boards) are analyzed. Combustion of this fuel produces 9% of solid-state ash containing low-melting compounds capable of infiltrating into the chamotte refractory. Because of the frequent thermal shocks associated with heat-cool operating regimes and the attack by molten ash slag, the chamotte lining undergoes degradation. To improve the operating conditions and extend the service life of the lining, the use of a castable monolithic material with superior resistance to high temperature and corrosion is proposed.
