END USER MARKETS: PROCESS PLANTS: UTILITY

The Power market has been analyzing the utilzation of IEC61508 and IEC61511 as well as considering tha adoption and integration of the ANSI/ISA 84 standard to:

Process Boiler (NFPA 85)
Fired Process Heater (API 556)
Incinerator (NFPA 86)
Oil Treater Heater (API 14C)
Glycol Reboiler (API 14C)

Plus:
FM7-45
NFPA 85, 86
API RP 556
British Health & Safety Executive Board (HSE)
Black Liquor Recovery Boiler Advisory Committee
EN 50156-1 Electrical equipment for furnaces and ancillary equipment
