The present twin water curtain fire control system is designed to prevent the fire from propagating into adjacent cars and areas in case of a fire incident. The system will encapsulate the fire between the twin water curtain sections in order to make the evaluation of people who may be trapped inside the tunnel possible. The present system is designed as a fire controlling system where the twin curtains will effectively stop the fire from propagation. The physics in this respect and the task is to create an effective water wall fire barrier. When hot smoke and air is reaching the fire curtain, the ambient temperature in this area will be significantly reduced as a function of rapid heat exchange/heat absorption. Water Curtain fire protection system, consisting of at least two water curtains, each curtain containing a plurality of nozzles, of which some of them are used for a high velocity water flow and the others are used for a low velocity water flow (flat cone nozzle) such that each curtain is forming a water barrier, whereby those curtains are located close together in a predetermined distance, for example in a distance between 0,5 metres and 20 metres. |
