| Abstract: | According to technological flue as denilrifieation device and by use of ozone Corrosivity testing device, the eormsivily shMv on racial materials is started in this paper. Through representation of surface topography of different materials before and after corrosion with scanning electro microscope, lhe corrosion eharaeleristies of ozone in different materials are determined. The adiabatic Ienl- perature rise of ozonolysis is delermined through lheoretic calculation. By combining the leehnological characteristics of denitrifieafion deviee, the flow velorily of oxygen pipelines is analyzed and sumnla rized. Thus, lhe suggestions are put forward according to the analysis resull. |
