2019-6-1  However, a high water pressure is often needed to realize efficient fire control in the hydraulic atomization technique, the widely used high-pressure water mist system generally requires a water pressure of about 10 MPa in producing water mist for fire suppression (Fan et al., 2002; Liao, 2008; Wang, 2015). This often leads to safety concerns as well as transport problems of the pressure supply system in coal
