Simulation on regenerative thermal oxidation of ventilation air methane
Abstract：In order to simulate the performance of the thermal oxidation process and optimize the essential parameters, a simplified single channel homogeneous combustion model with periodic boundary conditions and one step methane/ air reaction mechanism was proposed for a regenerative thermal oxidizer on laboratory-scale. The basic performance of regenerative thermal oxidation of ventilation air methane were calculated by the computational fluid dynamics （CFD） without a pilot stage. The results show that a ceramic bed of 0.3 m in length at one side is sufficient to operate proper- ly at these conditions. Distributions of temperature on steady and unsteady state condition were respectively simulated by computational fluid dynamics. The initial parabolic temperature distribution gradually evolved into a typical trape- zoidal distribution of temperature field after hundreds of switching cycles.
