Difficulties such as deviation of flow field, ununiformity of axial velocity and temperature often appeared in semidry FGD with circulating fluidized beds. These caused lower desulfurization efficiency and were important reasons for particles adhering to wall. The composite fluidization mode of swirl-once through flow in DCFB-FGD was applied in a 145MW unit to the difficulties. As a result, uniformity of axial velocity and temperature for composite fluidization mode in the experimental diameters are better than that of traditional venturi fluidization mode. Desulfurization efficiency of composite fluidization mode is increased with Ca/S molar ratio increased and approach to adiabatic saturation temperature decreased. The desulfurization efficiency can be higher than 90% at lower Ca/S molar ratio and higher approach to adiabatic saturation temperature. System can operates stable for long time with a little phenomena of particles adhering to wall. So it suits the request of the semidry FGD with circulating fluidized beds and has better foreground.
