Abstract
In this study, a mechanism for mercury chlorination in flue gases and fly ash particles resulting from the combustion of pulverised coal is presented. A reduced gas-phase reaction mechanism is combined with mercury heterogeneous oxidation on the fly ash particles. The mechanism is used in an advanced CFD model of a pilot-scale test facility and is validated by comparison to available experimental data for air-coal combustion conditions. The model is then used to simulate mercury speciation under oxy-coal combustion conditions. This approach aims to provide an improved prediction of mercury speciation from coal-fired power plants and to elucidate the changes to mercury speciation encountered during oxy–coal combustion.
