森林火灾对站场热辐射的危害问题越来越突出,在站场周边开辟防火隔离带是减少火灾热辐射危害的有效方式之一。合理确定站场防火安全距离,不仅可以确保站场安全,还可以节约土地资源。采用固体火焰辐射模型和热辐射伤害准则,建立了森林输油站场防火安全距离的计算模型。应用该模型,计算了不同距离处森林火灾对于漠河输油站场的热辐射通量,分析了火灾火线强度、火焰倾角及火焰温度等因素对于防火安全距离确定的影响作用。以漠河站为例,计算得出了防火的安全距离,为确定森林输油站场防火安全距离提供了有效的参考依据。
The fire hazard of forest fire to heat radiation in station is becoming more and more prominent. It is one of the effective ways to reduce fire hazards caused by heat radiation in the surrounding area. Reasonably determine the fire safety distance station, not only to ensure station safety, but also can save land resources. Based on solid flame radiation model and heat radiation damage criterion, a computational model of fire safety distance in forest oil delivery station was established. The model was used to calculate the thermal radiation fluxes of forest fires at different distances to the Mohe gas station, and the effects of fire line intensity, flame dip angle and flame temperature on the determination of fire safety distance were analyzed. Taking Mohe station as an example, the safety distance of fire prevention is calculated, which provides an effective reference for determining the fire safety distance of forest oil pumping station.
