Modern burning technology for cement plants

Modern combustion technology permits extremely flexible reaction to the varying properties of alternative fuels.

In many parts of the world, the use of alternative fuels is a recognized measure for reducing the CO₂ emissions that result from burning primary fuels such as coal, oil and natural gas. Alternative or secondary fuels are the terms used for combustible residues from industrial and commercial manufacturing processes, agricultural production, and sorted municipal refuse. Due to the wide range of possible sources of alternative fuels, there is very great variation in their energy content, ash, moisture content, particle size, form, density etc., so there is no patent solution for their use in a...
