Indigo Agglomerator Reducing Particulate Emissions & Reducing Opacity
Agglomerator Is Like An ESP • Grounded plates • Discharge electrodes • Alternating arrangement • High voltage energization • Low pressure drop
Agglomerator Is Not Like An ESP • No collection • No hoppers • No rappers • High velocity / small size • +/- high voltage • Low power consumption
THE BENEFITS • Reduced mass emissions • Reduced visible emissions • Greater compliance safety margin • Increased choice of fuel supply • Higher tolerance for • Boiler upsets • Lost electrical sections of ESP
