Abstract: Fire fighting practices of charcoal powder stacks have shown that traditional disposal measures such as jet water, flowering water, and foam cannot extinguish the fire, and are likely to cause dangerous situations. This paper summarizes the fire characteristics of charcoal powder stacks through experimental observations, compares and verifies the fire extinguishing effects of different fire extinguishing agents under different application methods, the results show that for the charcoal powder stacking at the fire site, ventilation conditions should not be rashly changed, at the same time, personnel should not approach the disposal rashly. The embankment cofferdam and pouring the water-based fire extinguishing agent foam or fire extinguishing gel can form a full coverage, thereby effectively control the charcoal powder stacking fire.

Key words: charcoal powder, stacking, fire characteristics, embankment cofferdam, full coverage
