A Study on the Effect of Compartment Airflow and Obstacles on Combustion Shape

The fire department and the police began a joint study on an unusual natural fire extinguishing incident that occurred at an actual fire site, and were able to obtain results that resolved questions at the site. In this study, through fire reproduction experiments and simulations, it was confirmed that when a fire breaks out in a compartment, artificial air flow moves the decomposed gases generated from combustion to prevent a chain reaction from occurring, thereby hindering the growth of the fire. In addition, the human body requires a lot of energy and oxygen for thermal decomposition, which has proven to be an obstacle to combustion progress in compartment fires. In addition, through this study, the expected burning time of a naturally extinguished fire in an 18.4㎥ compartment is 6 minutes 30 seconds to 7 minutes 40 seconds, and it takes up to 4 minutes 30 seconds for carbon monoxide to reach 500 ppm, and the depth of damage to human skin It provided a basis for inferring the direction of combustion according to.
