Abstract

Virtually complete bonding of salt-forming agents to solids during the combustion of fossil fuels, waste or the like by adding basic solids, in particular CaCO3 or MgCO3, can be achieved by the following process steps: the moisture content of the fossil fuels, the waste or the like is adjusted to 10 to 35% by weight; the basic substances are added to the fossil fuels, the waste or the like in the most uniform distribution possible, the stoichiometric ratio of basic substances to salt-forming agents being less than 5:1; after the basic substances have been added, the fossil fuels, waste or the like remain in an essentially sealed container, so that a state of water vapor saturation is obtained; the mixture is then burnt at a fuel bed temperature below the thermal dissociation temperature of the compounds resulting from the basic substances and the halogens.
