A batch of around 150 g of raw meals has been fed into the reactor during each calcination experiment. Flows of about 0.35 Nm 3 h −1 of carrier gas (coming from a compressor at 5 bar) and between 0.2 and 1 kg h −1 of solids have been injected during the calcination tests. Both solids and carrier gas have been preheated up to 500 °C before they entered the reactor.
