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

Effect of alternative fuel properties on NOx reduction
(Conference report, 2002)Today we see a substantial increase in the use of alternative fuels in the cement industry. The prospect of reduction in fuel costs and the environmental benefits of waste to energy conversion are the driving forces. For ... -
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 ... -
The impact of staged combustion on the operation of a precalciner cement kiln
(Doctoral theses at NTNU;1999:89, Doctoral thesis; Peer reviewed, 1999)In this thesis, the impact of staged combustion on the operation of a precalciner cement kiln, is considered. Mathematical modelling and full-scale experiments at the Norcem cement works in Brevik, Norway, is the basis for ...
