摘要:
为评估掺氢天然气的燃爆风险，搭建天然气掺氢燃爆参数测试平台，通过开展不同初始压力及点火能量条件下天然气/氢气混合物的点火实验，研究多组分天然气爆炸下限的变化规律，建立混合物爆炸下限的预测模型。研究结果表明：初始压力由0.03 MPa增至0.1 MPa，体积分数4%的天然气起爆时所需最低掺氢量降低29.4%；点火能量由1 J增至50 J，体积分数4%的天然气起爆时所需最低掺氢量降低37.5%，本文提出的理论模型预测结果与实验数据相对误差低于16%。研究结果可为掺氢天然气的安全输送提供一定的科学参考。
Abstract:
In order to assess the explosion risk of hydrogen-blended natural gas,a testing platform for the explosion parameters of hydrogen-blended natural gas was constructed.The ignition experiments were conducted on natural gas/hydrogen mixture under different conditions of initial pressure and ignition energy,then the change law of the lower explosion limit of multi-component natural gas was studied,and a prediction model for the lower explosion limit of the mixture was developed.The results show that as the initial pressure increases from 0.03 MPa to 0.1 MPa,there is a reduction of 29.4% in the minimum hydrogen blending ratio required for natural gas explosion with a volume fraction of 4%.When the ignition energy increases from 1 J to 50 J,there is a reduction of 37.5% in the minimum hydrogen blending ratio required for natural gas explosion with a volume fraction of 4%.The relative error between the predicted results of theoretical model proposed in this paper and the experimental data is less than 16%.The research results can provide a scientific reference for the safe transportation of hydrogen-blended natural gas.
