An overview of hazardous-area applications across power plants, fuel handling systems and auxiliary facilities.
DESCRIPTION
Specific areas in power generation facilities contain natural gas, hydrogen, fuel vapours, oil mists, or combustible coal and biomass dust. Gas and vapour areas are classified as Zone 0, 1 or 2 under IEC/ATEX, or Class I, Division 1 or 2 under NEC; dust areas are classified as Zone 20, 21 or 22, or Class II, Division 1 or 2. Electrical equipment must match the assigned classification, substance group and temperature limit.
