As a result of examining chlorine fixation performance at high temperatures and combustion (oxidation) catalytic property of hydroxyl sodalite (Na_8(AlSiO_4)_6(OH)_2) and hydrogrossular (Ca_3Al_2(SiO_4)_<0.8>(OH)_<8.8>) using the laboratory scale reactor, it was confirmed that both materials had each function. The confirmation test of HCl removal at high temperatures and dioxins formation control in the flue gas was carried out using the fixed bed and the fluidized bed equipment of the large scale. As a result of the test, it was confirmed that the HCl gas in flue gas could remove at high temperatures and the dioxins concentration effectively decreased. From the facts described above, we may conclude that the reduction of HCl concentration and the combustion of the dioxins precursor are effective for the dioxins formation control.
