New Method of Coal Comminution to Ultrafine Size

Abstract

Research into the use of coal for power generation has become more important to deliver next-generation solutions for advanced coal cleaning technologies required by near-zero emissions. Comminution of coal with waterjets to ultrafine particle size offers a new and promising method for producing coal-water fuel (CWF), which is a replacement for power generation products. In this paper the results of coal comminution in a waterjet-based mill are presented for the range of pressures up to 276 MPa using four groups of feed size ranging from minus 850 micrometers to less than 106 micrometers. The focus of studies was on particle size reduction and distribution. The results presented in this paper are part of ongoing studies of coal-water fuel optimization for power generation.
