- Výzkumný ústav pro hnědé uhlí a.s., Most
The paper describes the method of mechanical slag dewatering, where the process water circulates in a closed circuit. This unique method was implemented at Mělník power plant according to a documentation developed by the following companies: Výzkumný ústav pro hnědé uhlí a.s. and CAB minerals, spol. s r.o. The slag is dewatered with the use of a vibratory screen separator and a hydrocyclone. Water that conveys the slag from boiler to pump stations is refined and returned to the process. The refining process has several stages. The first stage is represented by hydrocyclones, the last stage is flocculation including dosing station and sedimentation basins.
