Prevent fires, explosions, and implosions in heating equipment with the revised 2007 NFPA 85! Complete with a time-saving chapter on common requirements for all boilers, NFPA 85 contains important provisions for boiler design, installation, operation, training, and maintenance. Updated for 2007, this comprehensive document applies to the full range of large boilers and systems, including: 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. Changes to the 2007 edition include: An expanded scope includes all combustion turbine exhaust systems, not just heat recovery steam generators New requirements for flue gas path auxiliary systems, including, but not limited to ammonia injection, sulfur burners, soot cleaning systems, and electrostatic precipitators Relocation of furnace structural design requirements from the common section of Chapter 4 into the various related Chapter New furnace structural design requirements for multiple burner boilers now include the impact of booster fans Added requirements for fuel gas and fuel oil safety shutoff valves Consolidation of commissioning and installation requirements into a single section minimizes duplication
