电暖器对毛毯和报纸的引燃能力研究

Ignition capability of electric heater on blanket and newspaper

为了研究五面卤素管电暖器的引燃能力,选取毛毯和报纸为可燃物,实验研究了五面卤素管电暖器在不同功率和不同距离条件下引燃可燃物时的试验现象及表面温升情况。结果表明:毛毯和报纸表面温度在5 min左右达到稳定状态;距离为0时,毛毯被引燃;距离为0,功率为2 000 W时,电暖气着火;报纸未被引燃。研究发现,五面卤素管电暖器的功率越大,引燃距离越小,可燃物表面温度就越高,引燃能力就越强。

In order to study the ignition capability of five surfaces halogen tube electric heater, blankets and newspapers were chosen as combustible, the combustion phenomenon and temperature under different power and distance were experimentally studied. The results showed that, the temperature of blanket and newspaper reached stable after 5 min; when the distance was 0, the blanket was ignited; when the distance was 0, and the power was 2 000 W, the electric heater was on fire; the newspaper wasn＇t ignited. The research found that the bigger the power is, the shorter the distance is, the higher the surface temperature would be, and the stronger the ignition ability would be.
