KHD combustion chamber – flexible use of alternative fuels in the cement plant

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...

Proven experience with alternative fuels in the cement kiln process

In times of increasing energy costs, it is of vital interest for any company to save energy. To cut the energy costs for clinker production, the German cement industry started substitution of primary fuels with Alternative Fuels (AF) such as used oil or tyres after the first oil crisis of 1973. Today, alternative fuels and raw materials (AFR) include a wide range of types of hazardous and non-hazardous waste...
