Abstract

AbstractThe slurryability, rheological properties, stability, and combustion characteristics of coal water slurry (CWS), made from coking wastewater (CW), deionized water, and Shenhua coal were experimentally studied. Results showed that the solid concentration of coal‐coking wastewater‐slurry (CCWS) could be higher than 60.5 %, which is 0.5–1.5 % lower than that of coal water slurry (CWS). However, the pseudoplastic behaviour of CCWS was greatly evident. The dispersion effects of NNO and NDF were excellent. The stability of CCWS is better than CWS. Moreover, CCWS had lower ignition temperature and burnout temperature, higher combustion characteristic parameters, such as combustion characteristic index S and ignition stability index Rw, and better performance in combustion than CWS. The application of CW for the production of coal water slurry demonstrated the resource utilization of wastewater and improved the combustion characteristic.
