【摘要】 活性炭的燃烧初期会生成大量CO₂和CO,通过对浸渍活性炭燃烧烟气中CO和CO₂浓度的测量及分析,结果可知,在核电厂通风系统中碘吸附器的下游适当位置设置CO探测器可以较早地发现初期着火现象,从而可以及时采取下一步的防护措施而避免碘吸附器火灾所造成的进一步危害。更多还原

【Abstract】 A large amount of CO₂ and CO will be generated in the early stage of combustion of activated carbon. The measurement and analysis of CO and CO₂ concentrations in the off-gas of activated carbon combustion were done and the results suggest that a detector of CO located in the suitable downstream of iodine adsorber in ventilation systems of nuclear power plants can dig out fire in its very early stage,therefore the next protective measures can be executed in time to avoid further hazards engendered by bigger fire of iodine adsorber.更多还原
