Cotton and polypropylene, the typical organic components of medical waste were incinerated with the addition of inorganic bromine in this experiment. It has been found that the incineration temperature is an important factor affecting the migration characteristics of Bromine. Bromine can be fixed by cotton at high temperature stage during combustion. The migration of Bromine from the mixture of NaBr and polypropylene during incineration can be divided into two stages. The mixture of NaBr and cotton can be divided into three stages. The low conversion rate of inorganic bromide to HBr was found in this paper, but quite a large
