Impact of size and temperature on the hydrodynamics of chemical looping combustion

Impact of size and temperature on the performance of pneumatic valves (L-valve and loop-seal) are investigated using valves in a range of 2-24 cm in a temperature range of 25-750 °C. Geldart group B particles of 100-300 μm and density of 2600-4750 kg/m3 are used in these experimental tests.
