Two Turkish lignites which have different sulfur levels (2–2.9% dry) and ash levels (17–25% dry) are combusted in a CFBC. Forest red pine chips in a 750 kW-thermal capacity CFBC system was co-combusted with lignites. Limestone was added, Ca/S = 3, to lignites to reduce SO2 emissions. CO emissions are high at low excess air ratios, gets lower as the excess air ratio increases. During co-firing experiments the temperature in the freeboard is 100–150 °C higher as compared to coal combustion.
