Experimental Investigation of Based Oxygen Carriers Used in Continuous Chemical-Looping Combustion

Figure 2

The reactor. Arrows are showing the flow direction of the particles. The air reactor is in blue, the fuel reactor is in red, and the downcomer and slot loop seals are shown in green. The pipes are the various gas inlets. In the slot and downcomer the bottom gas inlets consist of two separate pipes in order to distribute the gas evenly between the fuel reactor and air reactor side. In the downcomer one additional gas inlet sits at about half height and can be used in case of fluidization difficulties. Not shown in the image is the widened settling zone where the gas velocity is reduced so that particles fall back down into the reactor. Image courtesy of Patrick Moldenhauer.
