Full Description


Improve fire safety and system reliability with the 2011 NFPA 85: Boiler and Combustion Systems Hazards Code.

Updated for 2011, this comprehensive document applies to the full range of large boiler installations and pulverized fuel systems:
  • Large boilers, including atmospheric fluidized bed boilers with a minimum fuel input rating of 12.5 million Btu/hr (3.6 MW)
  • Stoker operations
  • Pulverized fuel systems
  • Fired or unfired steam generators used to recover heat from combustion turbines

Major changes for 2011 include:
  • New definition and rules for a Combustion Turbine Purge Credit enabling designers and operators to establish and maintain a "purged" condition for heat recovery steam generators between restarts
  • Streamlined requirements for continuous trend display for single burner boilers
  • Revised boiler requirements for purging the boiler enclosure where no fans remain in service
  • Expanded guidance on burner management system design describes the types of signals and transmitters used to initiate safety alarms and interlocks and appropriate monitoring methods
  • Added guidance regarding flue gas analyzers installed in the flue gas stream
