vapor diffusion

On the assumption that pipeline was burst completely,the leaking quantity was calculated using the two-phase-flow leaking expression of Risk Estimate Rudder,and accidents which were likely to happen just like jet conflagration,explosion and smoke-cloud diffuseness were forec.

假设管径完全破裂,采用风险评价导则中的两相流泄漏计算公式计算泄漏量,同时对泄漏过程中可能发生的喷射火焰、爆炸、蒸汽云扩散等事故采用相应的公式进行预测。

Three geothermal power technologies, namely, dry steam, flashed vapour and binary circulation geothermal power technologies as well as their features are discussed in this paper.

论述了干蒸汽发电、扩容蒸汽发电、双循环式发电3种地热发电技术及其特点;从所需地热温度、热效率、开采难度、环境污染、设备及其腐蚀性等方面,对3种地热发电技术进行了对比分析;最后简述了地热发电技术的发展方向与应用前景。
