The decomposition temperature exceeds 850 °C (nearly the application limits of refractory steel alloys). Other calcinations (e.g. dolomite, gypsum, phosphate rock, meta-kaolin, clays, etc.) are less demanding since occurring at a lower calcination temperature and with an endothermic reaction heat that is significantly lower than the reaction heat of CaCO3, which is therefore considered as a relevant test case.The solar horizontal bubbling fluidized bed concept developed within the SOLPART research project can be used as a solar receiver-reactor.
