摘要: 放射性废物焚烧过程中,意外工况下可能发生燃爆,因此需采取有效的泄压措施确保内部压力处于安全范围内。本研究选择爆炸特性与放射性废物热解气相似的甲烷作为实验气体,模拟焚烧炉爆燃条件,开展模拟泄爆实验研究。结果表明:在泄爆口开启压力为0.5~2.0 kPa范围时,泄爆口开启压力对最大泄爆压力的影响可以忽略;在不考虑泄爆管道影响的条件下,当泄放压力、气体性质和容器结构特征确定时,最大泄爆压力与泄爆口面积和内表面积之比成幂函数关系;泄爆系统内部空间的缓冲会对最大泄爆压力产生较大影响。

Abstract: Deflagration or explosion is possible in the radioactive waste incineration furnace in some unexpected conditions and accidents. The venting measure is necessary to decrease the furnace inner pressure of deflagration and explosion into a safety scope. In order to learn the explosion venting process and the main factors, CH4 of similar combustion feature with the waste pyrloysate gas, is used as the simulative gas in the certain explosive condition to simulate the deflagration or explosion process. The result shows: the peak inner pressure of incineration furnace is nearly invariable when the vent open pressure is in 0.5—2.0 kPa. The peak inner pressure is the power function of the ratio of the vent area and the inner surface area if the vent open pressure,the gas characteristic and container shape are confirmed and the effect of venting tube is not considered. However, the venting tube and the buffer space out of the furnace are significant to venting process.

Key words: radioactive waste, incineration, explosion venting, vent open pressure, waste treatment
