| Abstract: | Research the emissions characteristics of PM2.5 in ferrous metal smelting and rolling processing industry, Taking ELPI to analysis the grains distribution and mass concentration of particles in the title gas on line. Got samples through automatic smoke tester. And took in-depth research on the morphology of the particles, gathered characteristic, chemical composition and phase composition. Provided strong basis for the impact of PM2.5 on health and analysed climate ,and analysis the emission sources of PM2.5 particle in Chinese industrial. |
