(OP)
Does NFPA 85 rule boilers up to 300 HP?

RE: NFPA 85 boiler rules

This is 2011 edition


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 2011, 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

RE: NFPA 85 boiler rules

NFPA 85 Boiler and Combustion Systems Hazards Code for large boilers,
is controlling above 12.5 million Btu/hr, while

ASME csd-1-controls-safety-devices-automatically-fired-boilers
is controlling below 12.5 million Btu/hr

There some exclusions in both.

373 boiler horsepower ~= 12.5 million Btu/hr

So your 300 HP boiler is covered by ASME CD-1, depending on your jurisdictions boiler safety code.
