TURBINE PROTECTION SUMMARY

This is What You Need to Know

NFPA 850:

Recommends the water application rate for turbine protection at .30 gpm/ft2.

FM Global Testing:

Full scale testing proved .30 gpm/ft2 was inadequate to protect turbines and recommends .40 gpm/ft2 (Bulletin 2006-06)

Dominion Testing:

Testing showed educting 3% F-500 Encapsulator Agent into the water at .20 gpm/ft2 extinguished the fire three times faster than plain water at .40 gpm/ft2.

UL Testing:

Tests conducted at Underwriters Laboratories in 2014 showed .45 gpm/ft2 would be a better recommendation.

UL Testing in 2014 showed supplementing an existing .30 gpm/ft2 suppression system with 3% F-500 EA is as effective as re-designing and installing a .45 gpm/ft2 water only system.

FM GLOBAL RISK ASSESSMENT

Fire Damage:

Inadequately Protected Turbine with R480 million in damages and 24 weeks of shutdown

Adequately Protected Turbine with only R1.8 million in damages and 2 weeks of shutdown

Figures are from FM Global. Recent studies suggest the damage for one power plant is more likely closer to $100 million with loss of generating capacity exceeding 52 weeks.
