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

Abstract

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 × 10−3 kg/m2 and 1.68 × 10−3 kg/m2, respectively. This work will provide valuable references for the optimization of refractories used in PASWVI.
