By increasing the production of new electrical and electronic equipment, old equipment will eventually become WEEE, so that the increase in the volume of the WEEE is now higher than the average growth rate of urban waste. WEEE is usually burned and its energy is used in power plants. Organobromine compounds comprise between 3 and 8% by weight of WEEE and mainly converted to HBr and Br₂ in the incinerator. However, these compounds, during the cooling of the flue gases, can form the PBDD/Fs in the post-combustion area of the furnace. Due to the many benefits of Oxy-combustion process, our group has developed a fluidised bed incinerator for burning the WEEE and plan to maximise HBr/Br₂ in the flue gas. Experimental results presented in the recent papers show that the combustion of the WEEE particles attains quickly to thermodynamic equilibrium. Thermodynamic modelling can, therefore, predict the concentration of brominated pollutants, particularly HBr, Br₂, HgBr₂, and Br˙ in the flue gas. In this paper, the effect of various parameters for increasing the HBr/Br₂ ratio in the flue gas has been investigated. The model shows that the addition of very small amounts of hydrogen in the post-combustion area can convert Br₂ and Br˙ into HBr.

通过增加新的电气和电子设备的产量，旧设备最终将成为WEEE，因此WEEE的增加量现在高于城市垃圾的平均增长率。WEEE通常被燃烧，其能量被用于发电厂。有机溴化合物占WEEE的3至8％（重量），并且在焚烧炉中主要转化为HBr和Br ₂。但是，这些化合物在烟道气冷却期间会在炉子的后燃烧区形成PBDD / Fs。由于氧气燃烧过程的许多好处，我们小组开发了一种流化床焚烧炉，用于燃烧WEEE，并计划将HBr / Br ₂最大化。在烟气中。最近发表的论文中的实验结果表明，WEEE颗粒的燃烧迅速达到热力学平衡。因此，热力学模型可以预测烟道气中溴化污染物的浓度，特别是HBr，Br ₂，HgBr ₂和Br˙。在本文中，已经研究了各种参数对提高烟道气中HBr / Br ₂比的影响。该模型表明，在燃烧后区域中添加极少量的氢气可以将Br ₂和Br˙转化为HBr。
