본연구는석탄화력발전소로부터배출되는약 20% 정도의 mill reject 산물로부터석탄을회수하여에너지원으로재활용하기위한마찰하전형정전선별기술을개발하는데있다. 연구결과회분함량 47%인 mill reject 산물로부터회분함량 15% 인정제석탄회를 66.23% 의석탄회수율로얻을수있었다. 또한 releases analysis 분석결과발전소에서요구하는회분함량 20% 이내에서석탄회수율을 80% 까지얻을수있는처리공정을제시하여, 본처리법의우수성을입증하였다.
Abstract
This study was to develop the triboelectrostatic separation technique to recycle the coal from about 20% of mill reject products remained by grinding process in the coal thermoelectric power plant. In this study, we get a test results that can product the cleaned coal of 15% ash content and 66.23% recovery from mill reject of 47% ash content. And then, from the result of the releases analysis, we proved the excellence of treatment method, after showing the treament processing which is able to get 80% of recovery of coal from 20% of ash content demanded in the power plant.
