Abstract:

This research also publicized the assembly and installation processes to help reduce the time spent in future investigations. The biggest test chamber size after installation was 3 m high and 3 m wide. The experimental apparatus included temperature and pressure control functions, could reach temperatures of over 160°C within 17-23 minutes after initiating the experiment, and maintain a temperature of 200±20°C within 27-33 minutes. Liquid petroleum gas was used as the heating fuel. Pressure control satisfies regulated standards. The test chamber walls, fans and ventilation lines were made using sandwich-structured composites (steel plate + rock wool + steel plate) filled and sealed with heat resistant materials. Basic leakage of the apparatus was below 1 m³ / h, which was excellent sealing relative to the volume of the entire chamber. Three porous steel plates with different surface areas were used in the experiment to carry out basic volumetric leakage tests. Both theoretical and measured data were used to evaluate the accuracy of the experimental apparatus. Six types of fire proof steel doors and six types of fire proof wooden doors were used to analyze actual operations and leakage of the fire-resistant doors to understand the assessment capabilities of the experimental apparatus. Results showed extremely close leakage volumes under medium and standard temperatures when testing doors with fire proof properties. Leakages on either side of the experimental doors were also very close. The amount of leakage was directly correlated to the filling material used to seal the door gaps. This research also clarified the phenomenon where volumetric leakage would decrease with increasing temperature.
