Transcript of "Turbine suppression[2]"

  1. 1. Gas Turbine Fire SuppressionIntroduction to Products & Applications ROC Public: Green
  2. 2. Fire  Triangle   Oxygen   UNBREAKABLE CHAIN REACTIONHeat Fuel ROC Public: Green
  3. 3. Fire  Suppression  Systems  • Complete  Engineered  Fire  Suppression   Systems.   -  Detailed  System  Design  to  industry  codes  &  standards   -  Agent  Supply  and  Refill  Services   -  Clean  Agent  ,  Foam  &  Water  systems   -  Start-­‐up  Services   -  Long  term  Support  &  Service   -  Training.     ROC Public: Green
  4. 4. CO2  Fire  Suppression  Systems   •  VersaEle   •  Fast  &  Efficient   •  Clean   •  Low  Cost   ROC Public: Green
  5. 5. CO2  -­‐  The  VersaEle  Agent  •  Stored  as  a  liquid   -  CO2  is  stored  as  liquid,  under  pressure.       -  When  a  system  is  acEvated,  the  liquid  CO2   flows  through  discharge  pipe  work  to   specially  designed  nozzles.    •  Quick  VaporizaEon   -  The  agent’s  low  boiling  point  means  that   the  liquid  vaporizes  rapidly  during  the   discharge,  providing  a  penetraEve  three-­‐ dimensional  acEon.   ROC Public: Green
  6. 6. CO2  -­‐  The  VersaEle  Agent  •  Reaches  difficult  areas   -  The  rapid  expansion  of  the  gaseous  agent  allows   fires  to  be  targeted  even  in  the  most  inaccessible   areas  of  the  risk.  •  Fights  fire  on  two  fronts   -  Reduces  Oxygen:    Fire  is  exEnguished  by  reducing   the  oxygen  level  in  the  risk  area  to  the  point   where  combusEon  cannot  be  sustained.   -  Cools  Area:    Cooling  is  a  secondary  acEon  of  the   agent;  this  feature  is  used  in  local  applicaEons   where  the  liquid  phase  of  the  discharge  is   applied  directly  to  the  fire  and  risk  materials.   ROC Public: Green
  7. 7. CO2  -­‐  Fast  &  Efficient  •  CO2  is  fast  and  efficient   -  The  High  Pressure  CO2  system  uses  a  large  bore   discharge  valve,enabling  high  mass  flow  rates  to   be  achieved.       -  The  fast  acEon  of  the  control  system  and  valve   enables  the  system  to  react  within  the  first  few   seconds  of  a  fire  that  can  make  the  difference   between  a  nuisance  and  a  disaster.   ROC Public: Green
  8. 8. CO2  -­‐  A  Clean  Agent  •  CO2  clean:   -  CO2  is  a  colorless,  odorless,  dry,  inert  gas  and  is   one  of  the  most  familiar  of  all  chemicals.      •  No  residue:   -  AXer  exEnguishing  a  fire  it  vaporizes  fully  leaving   no  residue.    There  is  no  mess,  nothing  to  clear   up,  no  water  damage.      •  Safe  to  use  on  food:   -  It  is  non-­‐corrosive  and  will  not  contaminate   foodstuffs.       ROC Public: Green
  9. 9. CO2  -­‐  A  Clean  Agent  •  Safe  for  electrical  fires:   -  It  is  non-­‐conducEve  and  so  can  be  used  on   energized  electrical  equipment.     ROC Public: Green
  10. 10. CO2  -­‐  Over  60  years  of  Experience   •  Engineers  developed  carbon  dioxide  fire   ex5nguishing  over  60  years  ago  and  Kidde  have   been  responsible  for  every  major  improvement   that  has  been  made  in  this  branch  of  fire   protec5on.     •  Exis5ng  Products  benefit  from  the  accumulated   experience  of  thousands  of  installa5ons  in  power   plants,  industrial  plants,  oil  refineries,  electronic   processes,  on  ships  and  in  a  wide  variety  of   hazardous  areas.   ROC Public: Green
  11. 11. CO2  is  Low  Cost  •  Carbon  dioxide  is  a  standard  commercial  product   with  many  other  uses  and  it  is  readily  available   throughout  the  world.      •  Because  of  its  universal  use  it  can  be  obtained   cheaply  and  this  is  an  important  considera5on   when  frequent  recharging  of  storage  containers  is   necessary  as  in  local  applica5on  systems,  where   fires  may  be  more  frequent.   ROC Public: Green
  12. 12. Basic principle: WATER, discharged at HIGH PRESSURE through SPECIAL NOZZLESResulting in VERY SMALL DROPLET SIZE and HIGH DISCHARGE VELOCITY ROC Public: Green
  13. 13. A safe and fast alternative to CO2 A reliable alternative to inert gases A clean alternative to foamAn environmentally friendly alternative to halon ROC Public: Green
  14. 14. High  Pressure  Water  Mist  •  Safe  alterna5ve  to  CO2  •  CO2  has  impact  on  central  nervous  system  and  heart  func5oning  •  Normal  air  has  less  than  0.1%  CO2,  normal  breathing  rate  25-­‐30/min  •  0.5%  is  the  safe  limit  for  spaces  occupied  for  less  than  8  hours  •  Increase  to  3%  doubles  the  normal  breathing  rate,  causes  headache  •  12%  consistency  causes  loss  of  consciousness  rapidly  and  death  in  a  couple   of  minutes  •  CO2  fire  protec5on  systems’  consistency  is  min.  34%,  and  this  consistency   should  be  aTained  within  one  minute  (re.  NFPA  12),  and  maintained  over   the  en5re  protec5on  5me  (10-­‐40  minutes).  •  Fine  clean  water  mist  produced  by  HI-­‐FOG  is  safe   ROC Public: Green
  15. 15. High  Pressure  Water  Mist  •  Fast  alterna5ve  to  CO2  •  Use  of  water  allows  for  immediate  ac5va5on  •  Minimum  fire  damage   FIRE CO2-system HI-FOG 1. Evacuate & 1. Activate confirm 2. Secure enclosure 3. Activate 2-20 minutes Delay <1 second Delay ROC Public: Green

High  Pressure  Water  Mist  •  Environmentally  friendly  alterna5ve  to  halons  /   halocarbons  •  No  global  warming  poten5al  •  No  ozone  layer  deple5on  •  No  thermal  decomposi5on  products  (toxic,  carcinogenic,   corrosive)  •  Re-­‐fill  is  prac5cally  free  •  Re-­‐fill  is  easily  and  immediately  available  in  most   condi5ons  •  No  end  of  life  disposal  concerns   ROC Public: Green
