A small-scale experimental fire tunnel has been designed and constructed at CIMFR, Dhanbad India to understand the different aspects of fire dynamics. The tunnel is arch shape 65.5 m long and 5.86m2 in cross section provided with two cross cuts, sliding doors, fan and chimney etc. it is equipped with state-of-the-art computer aided on-line tele-monitoring system having 130 sensors to monitor the parameters like temperature, gas concentration, velocity of air, pressure drop across fire zone and fan pressure, heat flux, smoke density all along the tunnel length. A data acquisition system comprising data-loggers, software and computer etc. have also been provided. Experiments for coal fire studies under varied airflow rate were carried out in the tunnel to understand the dynamic phenomenon of open fires and to evolve a suitable fire suppression technique. If such monitoring system will be installed in any road or rail tunnel, can enhance the safety of the tunnels with regards to fire. Further if any fire breaks out in road or rail tunnels, fire suppression techniques like HPHS nitrogen foam and water mist technology can be used to suppress the fires.
