Physical and simulated impacts of fires strait piping column apparatuses (post 2)

This paper presents the results of the physical and mathematical modeling of the pool fire influence on the processing unit pipeline system. To perform a physical test of the vertical vessel piping, an experimental unit with geometric proportions of the real system was created. Pool fire was simulated by burning the kerosene-diesel oil mixture. Temperature change in pipeline system elements were measured with a thermal camera. The results of the physical experiment were used to improve the initial conditions in the ANSYS FEA analysis. The model experiments revealed the trends in the pipeline system strain-stress state changing under various conditions of burning and fire extinguishing.
