AB Catalyst | Cleaner Coal Combustion

More complete burn, less fuel needed.. AB Catalyst optimizes combustion conditions to reduce fuel consumption. We typically see a 3 - 10% reduction in pulverized coal boilers and as high as 20% in chain boilers.. The catalyst lowers the ignition temperature and carbon burnout temperature of coal while generating more heat. Therefore, less coal is needed to maintain standard operating
