Abstract:

In order to study the effect of automatic sprinkler system on the combustion performance of floor covering materials in the early stage of fire, this paper used Fire Propagation Apparatus (FPA) to study the effect of water on the combustion performance of blended carpet in dry state, 50% moisture content state and full immersion state. The results showed that with the increase of moisture content, the ignition time of blended carpet increased, and the blended carpet with high moisture content was not easy to be ignited; The peak heat release rate in the water- containing condition was larger than that in the dry condition, the fire scale was larger, the total heat release in the flame combustion duration was smaller; Under the condition of water content, the peak value of the total smoke production and its components appears later.

Key words: combustion performance, heat release characteristics, smoke generation, dry and wet state, blended carpet
