“…During gasification, dolomite undergoes calcination to yield CaO, which acts to prevent agglomeration by favoring the formation of K2CO3 over K2OnSiO2 [24]. This effect was observed in gasification processes occurring at temperatures ranging from 650 to 850 °C, which were associated with optimal heating values, gas yields, carbon conversion rates, and cold gas efficiencies.…”

“…Research has shown that blending low-quality fuel with additives can lead to a decrease in the formation of solid particles and other combustion by-products, such as NOx, SO 2 , and HCl, during the combustion process [23].

This study investigates the combustion of agricultural biomass rich in alkali elements in the fluidized bed. The experiments were performed with smashed corn cob in a 500 kW fluidized bed combustor which was designed for work under low bed temperatures (650–700 °C). During the experiments, the formed compounds from corn cob combustion were measured by sampling particulate matter, and mineral compositions were determined. Also, the temperature profile of the FBC was established. It was determined that the emissions of K and Na elements from the FBC increased from 4 to 7.3% and from 1.69 to 3%, respectively, changing the bed temperature from 650 to 700 °C. Though alkali emissions are reduced at a 650 °C bed temperature, CO emissions are higher by about 50% compared to the case of 700 °C. The addition of 3% of dolomite reduced the pollutant emissions and alkali emissions as well. Potassium content decreased by about 1% and 4%, respectively, at the bed temperatures of 650 °C and 700 °C. The NOx emissions were less than 300 mg/m3 and did not exceed the limit for medium plants regarding DIRECTIVE (EU) 2015/2193. During extended experiments lasting 8 h, no agglomeration of the fluidized bed was observed. Moreover, the proposed configuration of the FBC and its operational parameters prove suitable for facilitating the efficient combustion of agricultural biomass.
