长输天然气管道放空火炬热辐射距离计算方法探讨

Discussions on the Calculation Methods of the Thermal Radiation Distance of the Flare Stack in Long Distance Natural Gas Pipelines

介绍了在考虑允许辐射强度和风速的影响因素下,长输天然气管道放空火炬热辐射距离的一般计算方法和Brzustowski-Sommer计算方法,并将计算结果与挪威船级社PHAST软件的计算结果进行分析比较,得出放空火炬热辐射距离一般计算方法的计算结果偏于保守,从而确定了长输管道放空火炬热辐射距离的计算,应以其一般计算方法为准。

The common and Brzustowski-Sommer calculation methods of the thermal radiation distance of the flare stack in tong distance nature gas pipelines were presented in consideration of the influences of permissible radiation intensity and wind speed. The calculation result was analyzed and compared with the result calculated using PHAST software developed by DNV. It was found that the was a little conservative, and this method should be used to calculate result of the common calculation method the thermal radiation distance of the flare stack in long distance natural gas pipelines.
