    Hi everybody!, I´m trying to implement a fire entinguishing system in the operating platforms of my DCU, we want to protect the people working there in the case of a fire with water splinkers. We want to place smoke and flame detectors as well as switchs to give the alarm and let the water come out. Does anybody have a system similar to this one??, If you can give me a hand I´ll be appreciated, we are having a lot of discussions and we don´t know how is done in other refineries. We also want to implement cameras to keep the eye on the operation in the platforms.
    Regards, Carlos

    Industrial Fire World has an article on how one refinery coker upgraded their switch decks and cutting decks with firewater moniotrs.  We are in the design process of a new delayed coker and have provided automatic deluge waterspray to cover both the plan areas of the Cutting Deck ans Switch Decks.  Each is a separate system specifically design for 0.3 USgpm/ft2 plan area.  The Cutting Deck required the installation of a booster pump to meet the residual flow pressure at the elevation of the Cutting Deck.  Our firewater system is able to meet the residual flow pressure requiements at the Switch Deck.  The flow hydraulics need to be carefully analyzed to make sure the flow and pressures are met.  We have also provided the option of supplying foam through 3x5inch Storz connections at both the Cutting Deck’s deluge valve system piping and the Switch Deck’s deluge valve system piping.  The use of our fire pumper trucks will provide the foam into the deluge piping systems.  Also, the decks deluge nozzles are those specifically approved (FM & UL) for water or foam applications.  Another key item to include is the ability to drain away the large flow of water either deluge system will flow onto the deck.  specific drainage downcomers need to be provided.  Our deluge systems will be automatically activated by any 2 of several optical fire-eyes located at each deck.  the requirement for 2 of several is to help prevent spurious trips.  Use of pneumatic pilot heads was considered infeasible due to the large number of such heads that would be required at each deck and all the air system piping and maintenance.

    We have a similar system with sprinklers on the top of the drums with fire detector. The problem with the fire detector is because some of them are located near some hot place. Because that, the sprinklers opened in the past. Nowadays we located outside of this place and there is no problem.
    The fire dector is the standard with liquid inside a glass.
    All this sprinkler is only to protect the man during a fire.

    We have a complete deluge system on our coker. We deluge around each bottom head, and walkways in this area. the switch deck  valves are also deluged. along with the top head deck . The deluge systems have multiple push buttons that the operators can activate. There are buttons located on both sides of the coker at the stairways  Each level is equipped with a  by-pass valves for testing that is done 2 times per year. The operators have a camera link to all deck levels. This deluge system is tied directly to the fire dept, where once activated we have immediate responce.
