Unreacted ammonia is commonly referred to as ammonia slip, breakthrough, or carryover. The amount of ammonia slip also depends in part on the amount of ammonia injected. Achievable NOx reductions for an individual boiler depend on the flue gas temperature, the residence time at that temperature, the initial NOx concentration, the NH3/NOx ratio

2021-1-7 · The fate of the ferrous ion (Fe2+) depends on condensate temperature, pH, and flow conditions. At low temperatures, Fe 2+ reacts with water to form insoluble ferrous hydroxide, Fe(OH) 2.If the condensate stream velocity is high enough, colloidal Fe(OH) 2 is swept into the water and car-ried downstream to deposit elsewhere. In low-flow areas of the condensate system, Fe(OH) 2 deposits
