Raw NaHCO3 was added to bituminous coal used as solid fuel for combustion in a pilot plant with circulating fluidized bed (0.1 MWt) at 850 degrees C (air flow rate 2.2 m/s). The Na/S mass ratio in the fluid blends was 1-3. the degree of SO2 removal was 93% and of NOx removal 46%. The NH4 salts present in the raw NaHCO3 were decompd. to NH3 and contributed to NOx redn. to N-2.
