Experience of Recovery Boiler Superheater Corrosion at

Black Liquor Recovery Boilers - An Introduction - NBBI - …

The potential for fuel gas explosions in BLRBs is similar to that of any large watertube boiler, and explosion experience has been greatly improved by application of fuel combustion control systems. Auxiliary fuel combustion control systems equivalent to the requirements of NFPA 8502, standard for the prevention of furnace explosions/implosions in multiple burner boilers, are recommended.
