Abstract

Based on the analysis of instrumental observation data, it is shown that large fires on gas pipelines manifest themselves in local variations in the amplitude of acoustic vibrations. The formation of a highly heated convective stream of gaseous products over a stationary combustion center provides an intensive supply of cold air into it. In this case, the formation of pressure and temperature gradients near the flame leads to the formation of vortex structures in the atmosphere and the generation of infrasound. An example of a severe fire on a gas pipeline in Moscow on May 10, 2009 is considered.
