Assessment of mercury emission at Norcem's cement kiln by use of 203 Hg tracer
(Conference report, 2005)In manufacture of cement clinker, mercury (Hg) is introduced in the cement kiln system via the fuels and as constituents in the raw materials, i.e. limestone, iron ore, etc. The permissible emission of Hg to air is very ... -
Assessment of sulphur emission at Norcem's cement kiln by use of 35S-tracer
(Conference report, 2001)Although sulphur is not a major reacting species in making cement clinker, it is introduced as a pollutant in both the energy carrier (oil, coke, coal, household waste) and in the reactants (chalk, silica). Due to the ... -
Burning chamber installation for increased use of alternative fuels at Norcem Brevik, Norway
(Conference report, 2006) -
Carbon dioxide emission reduction by increased utilization of waste-derived fuels in the cement industry
(Conference report, 2007)Considerable reductions in Norway's emissions of greenhouse gases like CO2 are required to meet the commitments of the Kyoto Protocol. CO2 emissions from cement clinker production originate from decarbonation of limestone ... -
Energy recovery from wastes : experience with solid alternative fuels combustion in a precalciner cement kiln
(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 ...
