크롬 전기도금을 통한 국산화 금속필터의 내부식성 향상 및 집진효율 특성에 관한 연구

다국어 초록 (Multilingual Abstract)

Fine dust is also generated with high temperature/high pressure syngas during coal gasification. The fine dust is usually removed by a conventional filter installed at the back end process of the sysngas production process and the filter is exposed to high temperature/high pressure syngas containing corrosive gases. The existing ceramic filter is resistant to such corrosion but it is quite vulnerable to mechanical and thermal shock while the metal filter is susceptible to corrosion by exposure to the syngas, resulting in short lifetime and frequent replacement. We thus developed a dust filter applicable to high temperature/high pressure syngas environment with improved corrosion resistance by applying ceramic coatings to metal filters. For that purpose, domestically produced metal filters were electroplated with chromium for enhanced corrosion protection and dust collection efficiency, which was experimentally examined for substantiation. As a result of the corrosion test, the corrosion resistance was improved in the metal filter electroplated with chromium. And this filter achieved a dust collection efficiency of 99.7% or more when applying the dust collector in the coal gasification process.
