Abstract

A new method for extinguishing fire is provided, characterized in that a pyrotechnic agent is used as a heat source (energy) and a power source (driving gas); during use, the pyrotechnic agent is ignited, and the high temperature generated by the combustion of the pyrotechnic agent is utilized to make a fire extinguishing composition produce a large amount of fire extinguishing substance, which is sprayed out together with the pyrotechnic agent, so as to achieve the purpose of extinguishing a fire. As compared with conventional aerosol fire extinguishing systems, gas fire extinguishing systems and water-based fire extinguishing systems, the fire extinguishing method of the present invention is more efficient and safer.

Claims (12)

1. A method for extinguishing fire, the method comprising:

providing a fire extinguisher having a nozzle for spraying out a fire extinguishing substance, a pyrotechnic agent and a fire extinguishing composition contained in the fire extinguisher, the fire extinguishing composition being disposed between the nozzle and the pyrotechnic agent within the fire extinguisher;

using the pyrotechnic agent as a heat source and a power source;

igniting, during use, the pyrotechnic agent to generate a high temperature gas; and

allowing the high temperature gas generated by combustion of the pyrotechnic agent to flow through the fire extinguishing composition to cause the fire extinguishing composition to generate a large amount of the fire extinguishing substance, which is sprayed out together with the pyrotechnic agent through the nozzle, so as to achieve a purpose of extinguishing a fire,

wherein the fire extinguishing composition includes 40 mass % of zinc carbonate, 50 mass % of potassium carbonate, and 10 mass % of microcrystalline paraffin wax.

2. A method for extinguishing fire, the method comprising:

providing a fire extinguisher having a nozzle for spraying out a fire extinguishing substance, a pyrotechnic agent and a fire extinguishing composition contained in the fire extinguisher, the fire extinguishing composition being disposed between the nozzle and the pyrotechnic agent within the fire extinguisher;

using the pyrotechnic agent as a heat source and a power source;

igniting, during use, the pyrotechnic agent to generate a high temperature gas; and

allowing the high temperature gas generated by combustion of the pyrotechnic agent to flow through the fire extinguishing composition to cause the fire extinguishing composition to generate a large amount of the fire extinguishing substance, which is sprayed out together with the pyrotechnic agent through the nozzle, so as to achieve a purpose of extinguishing a fire,

wherein the fire extinguishing composition includes 10 mass % of potassium nitrate, 15 mass % of phenolic resin, 55 mass % of sodium chloride, 15 mass % of hydroxyl-terminated polybutadiene, and 5 mass % of toluene diisocyanate.
