Usage pattern of jet fans for ventilation of railway tunnels
At impossibility or economic inexpediency of use of shafts ventilation of railway tunnels can be carried out with the help of the longitudinal scheme of the ventilation using jet fans. Alternates of jet fan distribution in railway tunnels are suggested for both electric and diesel locomotives.Examples are provided on identification of jet fan parameters in maintaining the required thermal and humidity conditions in the Lysogorsky tunnel, in decreasing the amount of natural draft in the Baikalsky tunnel and in removal of diesel combustion gases from the traffic section during operation of the Kuznetsovsky tunnel.
