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
