Digital PA for a refinery flare gas recovery unit and incinerator area?
Industry: refinery | Architecture: DIGITAL
The flare area of a refinery is an isolated, high-hazard location with Zone 2 gas classification, intense radiant heat from the flare stack, and limited personnel access. The BNA 8000 digital PA central exchange in the main control building manages the flare section as a dedicated zone. BNA 7400 flameproof horn speakers are installed at the seal drum area and incinerator fence boundary — meeting Zone 2 classification requirements. BNA 7301 outdoor horn speakers serve the safe-area perimeter around the flare exclusion zone. BNA 8100 master station in the control room allows the process engineer to broadcast flare exceedance alerts and emergency notices to maintenance personnel working near the flare area. BNA 500W amplifier with battery backup ensures continued broadcast during ESD events when the main power may be curtailed.
