Feasibility Study on a New Fire Extinguishing Technology with a Detonation Mist Jet

A fire extinguishing technology, the impulse water mist, has been successfully applied in the world. In order to raise its extinguishing efficiency and simplify its equipment, a new type detonation spray jet is developed based on explosion driven principle. Its working principle and dynamic performance, as well as the feasibility for fire extinguishment have been analyzed. The theoretical analysis and the primary experiment results indicate that the high speed and tremendous impact spray jet can be obtained from the strong power or instantaneous force driven by explosion, and the detonation spray jet has dual fire extinguishing performances of direct and spray jet. Its main fire extinguishing mechanism is the combined action of tremendous dynamic impact, high cooling efficiency, strong suffocation, thermal radiation absorption and flame elongation, so it has significant advantages to be developed as a highly efficient, clean and portable fire fighting tool.
