NFPA has opened both NFPA 86, Standard for Ovens and Furnaces, and NFPA 85, Boiler and Combustion Systems Hazards Code, to public input on the first draft of the next version of each standard. Both NFPA 85 and 86 are in the preliminary stage of revision, and the public is encouraged to provide feedback on items to consider or develop for the first draft of each standard.
NFPA 86 minimizes fire and explosion hazards of industrial ovens and furnaces. The standard addresses the safe design, installation, operation and inspection, testing and maintenance of Class A, B, C and D ovens, dryers and furnaces as well as thermal oxidizers and any other heated enclosure used for processing of materials and related equipment. Provisions are also provided for furnace heating systems, safety equipment and application, and fire protection. Those seeking to provide input for the first draft have until June 29 to submit input online.
NFPA 85 contributes to operating safety and prevents explosions and implosions in boilers with greater than 12.5 million BTU/hr, pulverized fuel systems and heat recovery steam generators. The provisions within the boiler and combustion systems code apply to boiler design, installation, operation, maintenance and training for large boiler installations and pulverized fuel systems. Among topics covered are the strength of the structure, combustion- and draft-control equipment, safety interlocks, alarms, trips and other related controls essential to safe equipment operation. Those seeking to provide input for the first draft have until Jan. 5, 2017, to submit input online.
