摘要:
为了研究不同喷射压力对乙烷喷射火火焰形态和热辐射范围的影响,进行30、35、50 mm喷嘴口径下乙烷喷射火的引燃试验,通过对喷射火的火焰高度、温度和热辐射强度进行监测,分析不同喷射压力下乙烷喷射火的燃烧规律。结果表明,随着喷射压力和喷嘴口径的增大,火焰高度和温度逐渐升高;在50 mm喷嘴口径、0.20 MPa压力时,火焰最高温度达到1 260 ℃;在30 mm喷嘴口径和0.15、0.20 MPa喷射压力时,距离火焰30 cm处热辐射强度超过25 kW/m2,达到可能致死的辐射量级。
Abstract:
To analyze the influence of different injection pressure on the flame shape and thermal radiation range of ethane jet fire, the ignition experiments on ethane jet fire with 30, 35 and 50 mm nozzle diameter were conducted. The combustion rules of ethane jet fire under different injection pressures were analyzed through measuring the flame height, temperature and thermal radiation intensity of the jet fire. Results show that when the nozzle diameter and the injection pressure increases, the flame height and the temperature increase, and the maximum flame temperature reaches 1 260 ℃ at 50 mm nozzle diameter and 0.20 MPa pressure. Under the 30 mm nozzle diameter and the 0.15 and 0.20 MPa injection pressure, the thermal radiation intensity at 30 cm away from the flame exceeds 25 kW/m2 and reaches a potentially lethal radiation level.
