The active foaming technology was described.The performance tests of wheeled extinguisher and heptafluoropropane foam extinguishing system in low boiling point flammable liquid fire, flowing fire and hot oil fire were carried out. The test results showed that the fire extinguisher and fire extinguishing system developed by the active foam extinguishing technology have less foam supply, higher extinguishing speed and better fire extinguishing effect compared with the traditional foam system and powder extinguisher, and the temperature of hot oil surface can be reduced to 17 ℃.%阐述主动发泡灭火技术,开展了由该技术制作的推车式灭火器和七氟丙烷泡沫灭火系统的性能测试,同时对低沸点可燃液体火灾、流淌火和热油火分别进行了灭火性能试验.试验结果表明,由主动发泡灭火技术研发的灭火器及灭火系统具有泡沫施放供给强度低、灭火速度快、降温效果好的特点,可使热油面温度降到17℃.
