Simulation of service environment and optimization of refractory lining for phenol acetone waste liquid incinerator

The service life of a phenol acetone salt-containing waste vertical incinerator (PASWVI) is largely dependent on the internal working conditions and the furnace lining refractories. In this work, the internal working conditions of PASWVI during the steady operation have been comprehensively investigated with aid of Ansys Fluent. Considering the effects of the waste fluid injection rate on both the high temperature zone of the furnace wall and the erosion of the furnace bottom, the waste fluid injection rate of 8 m/s is regarded as the suitable industrial operation condition. Based on this, the erosion rates of corundum-mullite brick and corundum-composite spinel brick for 1 h are calculated to be 3.60 x 10-3 kg/m2 and 1.68 x 10-3 kg/m2, respectively. This work will provide valuable references for the optimization of refractories used in PASWVI.

Automated summary

The internal working conditions of a phenol acetone salt-containing waste vertical incinerator (PASWVI) during steady operation were investigated using Ansys Fluent. The suitable industrial operation condition was found to be a waste fluid injection rate of 8 m/s. The erosion rates of corundum-mullite brick and corundum-composite spinel brick for 1 hour were calculated to be 3.60 x 10-3 kg/m2 and 1.68 x 10-3 kg/m2, respectively. This study provides valuable references for optimizing the refractories used in PASWVI.
