Status quo of fluorine pollution in atmosphere

as well as it’s prevention and control measures taken in China at present have been described. Directing against the problem of smoke form fluorine pollution

a dry method for fluorine-eliminating technology during combustion of coal has been put forward on the basis of summarizing methods taken at present. The said method adds fluorine-absorbing agents in the combustion process of coal. Results of test show that the fluorine-eliminating efficency of several developed fluorine-absorbing agents to be about 45～75%. In addition

the said agents have also the function of desulfurization

the max. efficiency of desulfuration being about 70%.
