COAL QUALITIES' INFLUENCES ON TRAITS OF COAL WATER MIXTURE

摘要

The influences of coal qualities, such as inherent moisture, pore rate, oxy-polar functional group, ash content, HGI, coal micro component and degree of coalification etc. , on properties of Coal Water Mixture (CWM) are introduced in this paper. The experiments related to effects of eight factors (carbon, hydrogen, oxygen, nitrogen, ash content, moisture, volatile matter and HGI) on CWM's slurriability were carried out and the prediction model of coal's slurriability was educed by multi-nonlinear stepwise regression method.
