【摘要】：基于海上某平台原排烟设计方案中存在的问题,进行了排烟设计方案优化。采用CFD软件对优化后平台高温烟气扩散及不同环境条件的运行工况进行了模拟仿真,分析了烟气温度及有害气体浓度的分布范围,结合CAP 437规范及人体接触有害气体限值,计算了温度升高导致直升机起降的不可使用概率和有害气体浓度危害程度及概率,最后探讨了缓解高温烟气危害的措施及排烟设计建议。本文研究结果可为海上平台高温排烟设计提供参考依据。
[Abstract]:Based on the existing problems in the original smoke exhaust design scheme of a platform on the sea, the smoke exhaust design scheme was optimized. The simulation of the platform's high-temperature smoke diffusion and operation conditions under different environmental conditions was carried out by using CFD software. The distribution range of flue gas temperature and harmful gas concentration is analyzed. Combined with CAP 437 code and the limit value of human exposure to harmful gas, the unserviceable probability and harmful degree and probability of harmful gas concentration caused by the rise of temperature for helicopter take-off and landing are calculated. Finally, the measures to mitigate the harm of high temperature flue gas and the suggestions for smoke exhaust design are discussed. The results of this study can provide a reference for the design of high temperature smoke exhaust on offshore platform.
