The Experiments With Cone Calorimeter

The carbon monoxide yield was 0.0194 kg/kg and carbon dioxide yield was 2.04 kg/kg. During the period from ignition to ignition plus the heat release rate reduced from 148.5 kW/m2 to121.3 kW/m2 in 6 minutes, effective heat of combustion increased from 35 MJ/ Kg to 37.6 MJ/ Kg during this period and mass loss rate decreased from 0.043 g/sec to 0.032 g/sec. The specific extinction area reduced from 750.3 m2/kg to 517.3 m2/kg, the carbon monoxide yield reduced from 0.0237 kg/kg to 0.0196 kg/kg and carbon dioxide yield reduced from 2.06 kg/kg to 2.04 kg/kg.The second blue carpet sample had a slightly lesser mass of 17.63 g with the same surface area and thickness as the first sample. The heat flux of the experiment was increased to 35 kW/m2. The time of the test was only 378 seconds and the total heat evolved was 34.9 MJ/m2. The total amount of oxygen consumed was 24.7 g and the amount of smoke released was 474 m2/m2. The mass lost during the experiment was 13.2 g with a specific mass loss rate of 5.09 g/m2s. During the experiment, the average heat release rate was 103.45 kW/m2 and effective heat of combustion was 20.88 MJ/ Kg. The mass-loss rate was 0.051 g/sec and the specific extinction area was 204.47 m2/kg. During these 6 minutes, the carbon monoxide yield was 0.0149 kg/kg and carbon dioxide yield was 1.21 kg/kg. During the period from ignition to ignition plus the heat release rate reduced from 268 kW/m2 to104.3 kW/m2 in 6 minutes, at the same time, effective heat of combustion increased from 13.7 MJ/ Kg to 20.9 MJ/ Kg and mass loss rate decreased from 0.203 g/sec to 0.051 g/sec. The specific extinction area decreased from 284.3 m2/kg to 204.5 m2/kg in 6 minutes, the carbon monoxide yield increased from 0.0136 kg/kg to 0.0149 kg/kg and carbon dioxide yield increased from 0.90 kg/kg to 1.21 kg/kg.
