摘要

由于基于木质纤维素样品表面上相对低强度火焰相互作用的方法通常不允许测量热释放率（HRR），因此提出了使用耗氧量热法的程序。该方法应用于放置在垂直位置的尺寸为320 mm x 140 mm x 25 mm的OSB样品。在测量过程中，除了HRR之外，还监测了燃烧器停止后显著的烟雾产生。在3 kW、4 kW和5 kW的燃烧器输出下，HRR的平均净值为2.339 kW，烟比消光面积在10.88 m2.kg-1和13.19 m2.kg--1范围内。

CHARACTERIZATION OF THE BURNING OF ORIENTED STRAND BOARDS EXPOSED TO FLAME

Since the methods based on the interaction of a relatively low intensity flame on the lignocellulose sample surface often do not allow measuring the heat release rate (HRR), a procedure using oxygen consumption calorimetry was proposed. The method was applied to OSB samples with dimensions of 320 mm x 140 mm x 25 mm placed in a vertical position. During the measurement, in addition to the HRR, the production of smoke, which was significant after stopping the burner, was also monitored. The average net value of HRR at burner outputs of 3 kW, 4 kW and 5 kW was 2.339 kW and the smoke specific extinction area was in the range of 10.88 m2.kg-1 and 13.19 m2.kg-1.
