A promising way to reduce CO 2 emissions of fossil‐fired power plants is the carbonate looping process with the reversible carbonation‐calcination reaction of limestone. The focus is on the gas release in an indirectly heat pipe‐heated calciner. Experiments in an electrically heated lab‐scale batch calciner demonstrated that transition from a fixed bed to a bubbling fluidized bed is possible without an external fluidization agent only by heating up limestone. Several indirectly heated calciner concepts are presented.
