Combined calcination and CO2 capture in cement clinker production by use of electrical energy

Tokheim, Lars-André; Mathisen, Anette; Øi, Lars Erik; Jayarathna, Chameera K.; Eldrup, Nils Henrik; Gautestad, Tor (Chapter, 2019)

The technical feasibility of electrifying the calcination process in a precalciner cement kiln system was assessed by studying different electrification concepts. Resistance-based heating was selected as it equires no CO2 ...
Energy recovery from wastes : experience with solid alternative fuels combustion in a precalciner cement kiln

Tokheim, Lars-André; Gautestad, Tor; Axelsen, Ernst Petter; Bjerketvedt, Dag (Conference report, 2001)

Today virtually all cement clinker burning processes take place in rotary kilns. A mixture of calcareous and argilaceous materials is heated to a temperature of about 1450 °C. In this process decarbonation followed by ...
