Abstract EN
Ammonium phosphate fire-extinguishing agents are one of the best substitutes for halon in many powder media.
Here, 11 μm median diameter ammonium phosphate ultrafine dry powder was used as a fire-extinguishing medium.
The fire-extinguishing performance of ultrafine powder under different pressures was studied by analyzing fire-extinguishing time, amount of extinguishing agent, and temperature during the fire-extinguishing process.
The results show that the fire-extinguishing performance of the ultrafine powder is improved with increasing injection pressure.
Finally, we used FDS software for fire simulation to study the influence of injection pressure on the extinguishing agent.
The results show that the extinguishing time is shortened with increasing injection pressure.
From 0.2 MPa to 1.0 MPa, the extinguishing time decreases from 34 seconds to 4 seconds.
