 Experimental study on industrial-scale CFB biomass gasificationXiaoxu Fan, Liguo Yang and Jianguo Jiang Renewable Energy, 2020, vol. 158, issue C, 32-36 Abstract: In order to reduce the CO2 emission of an existing 600MWe power plant in Hubei Province of China, a 30MWth biomass CFB gasifier was built to co-fire of the product gas in the pulverized coal boiler. Experiments were conducted with rice husks as the fuel. Different operation conditions, temperatures and loads, are investigated for their effects on the compositions, calorific properties, gasification efficiencies, carbon conversions and tar production. It was found that under the different working condition, the temperature curves along the riser height are similar, and temperatures at the bottom are higher than the top temperatures. The combustible components, calorific value and gasification efficiency of gas first increase and then decrease with temperature rise. The maximum calorific value and the maximum gasification efficiency of gas were 5751 kJ/Nm3 and 73.41%, respectively, at 789°Cand 814 °C. The gasification system runs smoothly under different loads, and the best gasification condition occurs at 30 MWth.
