Description

technical field [0001] The invention relates to the field of liquefied natural gas leakage and diffusion fires, in particular to an integrated experimental platform for liquefied natural gas leakage and diffusion fires. Background technique [0002] With the introduction of the "Twelfth Five-Year Plan" for natural gas, liquefied natural gas has been widely used. Liquefied natural gas has dual properties of low temperature, flammability and explosion. Once a leak occurs, low temperature natural gas is likely to cause personal injury. When encountering an ignition source, fire and explosion accidents may occur. In recent years, liquefied natural gas leakage and diffusion fire accidents have also occurred from time to time. Domestic research on the hazards of liquefied natural gas mainly uses numerical simulation methods, and relevant liquefied natural gas experiments have not yet been carried out, and credible experimental data are lacking.
