Research on fire test of train compartment based on multi-channel parallel calorimetric system

Abstract

Abstract The multi-channel parallel calorimetric system can ensure the test accuracy in the small-scale fire experiment, and also meet the measurement range of the large-scale fire experiment. Based on the test system of the railway rescue station, the solid and liquid combustibles were used for the real fire test, which were carried out outside the train compartment and inside the train compartment respectively. The real fire test was measured HRR, fire load, top maximum temperature. Through the comparison and analysis of the test data, the results showed that when the fire occurred in the confined space was harmer, so it was very important to do a good job of fire prevention and control in the confined space, especially in the tunnel. By comparing the combustion of solid and liquid, the damage of windows will increase the fire hazard.
