Study on flame propagation rules of combustible gas explosion in steel storage cabinets for hazardous goods

Abstract

Abstract: Conducted combustible gas explosion tests inside steel storage cabinets for hazardous goods, used FLACS to conduct numerical simulation research on the flame propagation of combustible gas explosion inside hazardous goods storage cabinets, and compared and analyzed the test results with the numerical simulation. The research results indicate that the flame propagation in the gas explosion test inside the steel storage tank is in good agreement with the numerical simulation calculation results. As the volume of the combustible gas increases, the internal flow field of the flame becomes more complex, and after the release plate is opened, the internal flame becomes more intense; External flames only appear when the combustible gas cloud inside the storage cabinet reaches a certain scale, and the amount of external flames emitted from the vent located further away from the gas cloud is greater than that from the vent located closer to the gas cloud.

Key words: hazardous goods storage cabinet, gas explosion, flame propagation, numerical simulation
