Experimental Study on the Combustion Characteristics of Deflagration and Pool Fire

In the survey stage of nuclear power plant site, it is necessary to consider the impact on nuclear power station brought by the aircraft. The most serious consequence is the fuel leak. The fuel combustion process is divided into two stages of deflagration and pool fire. Therefore, this paper studies the deflagration and pool fire combustion and its mechanism, the evaporation rate of aviation kerosene and Simulated Reactor gas surface temperature and pressure changes. The results show that flame will quickly generate pressure shock wave in the stage of deflagration. It will have a huge impact on buildings. Its instantaneous high temperature also has a large thermal load on the building through the radiation, convection and other forms.
