Reduction in light transmittance and visibility due to the obscuration of fine smoke particles
has been regarded as the most critical threat to fire life safety. Therefore, it is essential for
smoke control in underground spaces where electric cables are installed, especially for
cable tunnels, underground utility tunnels, subway tunnels, etc. This paper presents a new
method of fast elimination of cable fire smoke in underground tunnels using acoustic
agglomeration technology. First, the smoke production characteristics of typical electric …
