Fire extinguishing composition generating fire extinguishing substance through high-temperature decomposition

A fire extinguishing device wherein the fire extinguishing device comprising:

• a nozzle;
• and
• a composition comprising a pyrotechnic agent and a fire extinguishing composition placed within the fire extinguishing device;
• the fire extinguishing composition is arranged above the pyrotechnic agent within the fire extinguishing device closer to the nozzle of the fire extinguishing device,
• the fire extinguishing composition generates fire extinguishing substance by high-temperature decomposition, wherein the fire extinguishing composition comprises:
• a fire extinguishing material which can be decomposed to release a fire extinguishing substance with fire extinguishing properties during a heating process, the content of the fire extinguishing material being at least 80 wt %;
• wherein the pyrotechnic agent is adopted as a heat source and a power source in a process of fire extinguishing, the pyrotechnic agent is a pyrotechnic aerosol fire extinguishing agent, and
• wherein fire extinguishing is achieved by:
• igniting the pyrotechnic agent,
• generating a large quantity of fire extinguishing substance from the fire extinguishing composition in the use of high temperature produced by burning pyrotechnic agent, and
• the fire extinguishing substance spraying out together with the pyrotechnic agent.
