METHOD OF CALCINING A RAW MATERIAL TO OBTAIN A CEMENTITIOUS MATERIAL
A method of calcining a raw material to obtain a cementitious material, includes providing a flow of raw material containing a metal carbonate, such as CaCO3 to a calcination system, introducing the flow of raw material into a first thermal reactor and at least partially decarbonating the raw material in the first thermal reactor by subjecting the raw material to a first heat treatment at a first temperature of at least 650° C. in order to obtain an at least partly decarbonated material and CO2, wherein the first thermal reactor is heated by electrical energy, and obtaining the cementitious material as a result of the first heat treatment.
