3.2 Sensible heating of reactor
The dissociation of ZnO in a thermochemical reactor at various stages is shown in Fig. 3 (a). The
first phase starts with gradual sensible heating of reactor components such as the cavity wall and
multilayered insulation. During the second phase, reactor heating is stopped and the screw feeder is
extended into the reactor cavity in order to feed the granular ZnO particles uniformly over the cavity wall.
At the end of feeding the screw feeder is retracted and the power input is fixed to a constant maximum
