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

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

using a pyrotechnic agent as a heat source (energy) and a power source (driving gas);

igniting, during use, the pyrotechnic agent; and

utilizing the high temperature generated by the combustion of the pyrotechnic agent 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.

2. The fire extinguishing method according to claim 1, wherein the pyrotechnic agent is a pyrotechnic aerosol fire extinguishing agent.

3. The fire extinguishing method according to claim 1, wherein the fire extinguishing composition includes a chemical substance that is adapted to decompose while being heated and is adapted to release gas, liquid or solid particles that extinguish fire.

4. The fire extinguishing method according to claim 1, wherein the fire extinguishing composition includes chemical substance that is adapted to sublimate while being heated and is adapted to extinguish fire after sublimating.

5. The fire extinguishing method according to claim 1, wherein the fire extinguishing composition includes a chemical substance which undergoes a chemical reaction between the heated components to generate reaction product that can extinguish fire.
