| description | With the help of cone calorimeter, combustion experiments of 0# diesel and kerosene (3# jet fuel) under external heat radiation were completed, and the main combustion performance parameters, such as heat release rate, specific mass loss rate, effective heat of combustion, time to ignition, combustion duration and fire spread risk, were obtained under different heat source radiation intensities. The change rules of the main combustion characteristics of these tow fuels with the increase of heat source radiation intensity were discussed, and the differences of the main combustion characteristics between the diesel and kerosene were compared and analyzed. The results show that the average heat release rate, peak heat release rate and specific weight loss rate of the diesel and kerosene increase linearly with the increase of heat source radiation intensity, and the increasing trend (slope) of kerosene is larger than that of diesel. The time to reach the peak heat release rate, ignition time and combustion duration of the both fuels decreased exponentially with the increase of heat source radiation intensity. Under the same radiation intensity, the heat release rate, specific mass loss rate and effective heat combustion of kerosene are higher than those of diesel, while the time to reach the peak heat release rate, ignition time and combustion duration of kerosene are lower than those of diesel. The total heat release of kerosene is higher than that of diesel under different heat source radiation intensities, and the average total heat release of kerosene is about 6.17% higher than that of diesel. THR/tlastand pkHRR/TTI of the two fuels showed an exponential relationship, and the fire spread risk of diesel was less than that of kerosene. |
