摘要

摘要提出了一种预测烷烃在高压空气中可燃性上限的方法。通过绝热火焰温度计算模型确定了甲烷、乙烷、丙烷和正丁烷/空气混合物在环境温度和初始压力为0.3 MPa–2.0 MPa时的可燃性上限。给出了计算的绝热火焰温度与压力的关系，以确定可燃性上限。研究表明，具有压力相关性的预测可燃性上限与实验可燃性上限值之间具有良好的一致性。烷烃在高压空气中的可燃性上限估计值的平均相对误差达到2.52%。

Estimation of the upper flammability limits for alkanes in air at increased pressures

Abstract A method is proposed to predict the upper flammability limits for alkanes in air at increased pressures. The upper flammability limits for methane, ethane, propane and n-butane/air mixtures at ambient temperature and initial pressure of 0.3 MPa–2.0 MPa are identified through the adiabatic flame temperature calculation model. The association of calculated adiabatic flame temperature with pressure is presented to determine the upper flammability limit. Research shows the good agreement between the forecast upper flammability limits with pressure dependence and the experimental upper flammability limit values. The average relative error of the estimated upper flammability limits for alkanes in air at high pressures reaches 2.52%.

期刊介绍： Polish Journal of Chemical Technology is a peer-reviewed, international journal devoted to fundamental and applied chemistry, as well as chemical engineering and biotechnology research. It has a very broad scope but favors interdisciplinary research that bring chemical technology together with other disciplines. All authors receive very fast and comprehensive peer-review. Additionally, every published article is promoted to researchers working in the same field.
