Damage Analysis from Stress and Repair of the Annular Gas Channel Inner Partition of Coke Dry Quenching
摘要
Abstract
The transverse thrust loads of the annular gas channel inner partition caused by cokes were calculated based on the different packing situation of coke particles in the coke dry quenching.Stress fields of the annular gas channel inner partition were simulated by the finite element method with considering the pressure caused by the circulate cooling gas and coupling structure and thermal.The damage of refractories was analyzed from stresses.Results show that the temperature gradients and thermal stresses of annular gas channel inner partition increase with the increase of cooling gas flow rate;thermal stress is the main factor for deformation and crack of inner partition refractory materials because it is larger more than two times of structural stress.In order to avoid the further cracking and even collapse of inner partition,triangle support beams in the annular gas channel are installed.Then the suitable openings of different outlet plates for coke dry quenching are determined based on the calculated resistances to maintain the stability of furnace thermal system.关键词
