英文摘要The formation of slagging and fouling during municipal solid waste (MSW) incineration not only significantly affects heat transfer, but also results in shortened operating cycles. In order to solve the issues, the effect of different additives on the migration and transformation patterns of alkali/alkaline earth metals (AAEM) and chlorine during MSW incineration is screened based on the Gibbs energy minimization method. The effect of potential additives on the ash fusion temperature and combustion reactivity of MSW char is subsequently verified and evaluated by experimental methods. The thermodynamic equilibrium analysis shows that Al(NO3)(3), Ca(NO3)(2), and Mg(NO3)(2) have great potential to increase the ash fusion temperature. The experimental investigation confirms that the addition of Al(NO3)(3), Ca(NO3)(2), and Mg(NO3)(2) significantly increases the ash fusion temperature. The order of increasing the ash fusion temperature by different additives is Mg(NO3)(2) > Ca(NO3)(2) > Al(NO3)(3). The addition of Mg(NO3)(2) significantly increased the initial deformation temperature, softening temperature, hemispheric temperature, and flow temperature of ash from 1180, 1190, 1200, and 1240 degrees C to 1220, 1230, 1240, and 1260 degrees C, respectively. The addition of Cu(NO3)(2), Fe(NO3)(3), and KMnO4 significantly decreases the temperature at the maximum weight loss rate of MSW char, while increasing the maximum weight loss rate. Additionally, Cu(NO3)(2) shows the best performance in improving the combustion reactivity of MSW char. The addition of Cu(NO3)(2) evidently increases the maximum weight loss rate from 0.49 to 0.54% degrees C-1. Therefore, it is concluded that Mg(NO3)(2) and Cu(NO3)(2) are supposed to be the most potential candidates for efficient additives. This study presents an efficient and economical method to screen potential additives for alleviating slagging and fouling during MSW incineration.
