NFPA 8502-1999 PDF Download

NFPA 8502-1999 is a standard aimed at preventing dangerous explosions and implosions in multiple burner boilers. It specifically focuses on boilers that use pulverized coal, gas, and fuel with a minimum input of 12.5 million BTU/hr. This standard has been recently revised to address single fuels as well as the simultaneous firing of multiple fuels.

The main objective of NFPA 8502-1999 is to establish safety requirements that reduce the risks associated with combustion systems in boilers. These safety requirements include the use of interlocks and purging processes to minimize the likelihood of implosions and explosions in the furnace. The standard provides vital guidelines for ensuring the safe operation of boilers and preventing hazardous incidents.
