  • Removal of fireside deposits from the heat transfer tubes in kraft recovery boilers is carried out by sootblowing and occasionally "chill-and-blow" practices. During chill-and-blow, black liquor flow is reduced to rapidly cool the deposits. Thermal stresses generated in the deposit as a result of thermal shock can effectively weaken the deposit, facilitating its cleaning. For this study, we investigated the mechanical weakening effect of thermal stresses generated by the transient temperature… CONTINUE READING
