| Outline of Final Research Achievements |
In the Great East Japan Earthquake that occurred in March 2011, many fires were occurred. If fires occur in multiple and simultaneous due to the tsunami, there are cases where firefighting cannot keep up. As a countermeasure, we have proposed placing the small package type fire extinguishing equipment to each household. We have proposed plant biomass foam extinguishing method. This extinguishing method is assumed to be used for small packaged extinguishing systems for installation in general residential.
When using a vegetable oil or kerosene as fuel, extinguishing time is decreased as compared with the case of using as a fuel n-heptane. In a high boiling point fuel case, much foam was collapsed. Because the radiation intensity from high boiling fuel flame to foam is higher than n-heptane flame. Then, the heat balance in the condensed phase was examined. This result shows that the cooling of condensed phase is more important for extinguishing a high boiling point fuel fire.
