Attapulgite suspension mitigates fine particulate matter (PM2.5) emission from coal combustion in fluidized bed

Spraying attapulgite suspension in bed effectively reduces fine particle emission during coal combustion. 93.5% reduction in PM2.5, 93.6% in PM1 and 93.7% in PM0.1 is achieved with 38 ml/min attapulgite suspension spraying in dense bed.444
