FINDING RELIABLE SUPPLIES FOR ENERGY-INTENSIVE PROCESSES

摘要

Cement manufacturing is particularly energy-intensive. In order to reduce the use of expensive primary fuels such as coal and oil, cement plant operators are increasingly using alternative fuels and raw materials (AFR). In order to help customers efficiently convey, store and dose the treated fuels, BEUMER Group has established the new business segment called AFR systems Besides mineral waste that can be used as alternative raw material, the market primarily employs the use of fuel alternatives, because approximately 30 per cent of production costs are spent on energy. In addition to fluid alternative fuels, such as used oil or solvents, the majority of solid fuels consist of complete or shredded scrap tyres, scrap wood, or mixtures of plastic, paper, composite materials or textiles. After they have been treated and quality-controlled, they show calorific values similar to brown coal.
