Index

Applies to boilers with fuel input greater than 12,500,000 btu/hr (3663 Kw) or greater. This standard applies only to boilers using single burners. This standard establishes minimum requirements for the design, installation, operation and maintenance of single burner boilers, their fuel-burning systems, and related systems to contribute to safe operation and, in particular, to the prevention of furnace explosions.
