| Summary: | 碩士 === 國立成功大學 === 環境工程學系 === 107 === The emission of raw material operations is the main source of fugitive particle in integrated steel plant. However the emission factor formulated by the EPA mainly refer to foreign research, the climatic conditions and emission sources is different from that in Taiwan, so may result in a miscalculation of emissions. Therefore, establishing a self-factory emission factor can correctly estimate the actual emissions.
In order to measure the emission coefficient in the field, the study was conducted at the raw material storage yard of a factory in Kaohsiung in December, 2018; January, 2019 and May,2019. The basic principle of the experiment is the mass balance method, the concept is that, source emissions is the difference of concentration between up and down wind. The sample method is set up high volume sampler and PQ200 to sample TSP and PM2.5. additionally, this study used the aerial work vehicle which mount the pulley, and use the climbing rope to hang the optical particle counter, and measure the vertical direction concentration by pulling up and down.
According to the local measurement results of this study, loading dust has larger emission factor than unloading dust and pile wind erosion dust. And the emission factor of each emission behavior can be imply by multiple linear regression to obtain an emission factor estimation formula related to the impact factor, which can reflect the emission factor under different conditions.
