method for binding of salzbildnern solids in the combustion of fossil fuels, garbage 2)

摘要

A process for bonding halogens to solids in the combustion of fossil fuels, rubbish and the like with the following steps: the moistening of the fossil fuels, rubbish or the like; the addition of basic substances, especially CaCO3 or MgCO3 in as finely divided form as possible; allowing the fossil fuel, rubbish or the like to lie to produce the most complete neutralisation reaction possible between the halogens and basic substances, especially in a largely closed vessel in which a state of water vapour saturation is attained; combustion of the mixture at a hearth temperature below the thermal dissociation temperature of the compounds consisting of the basic substance and the halogens; is improved with respect to the desired neutralisation reaction between the halogens and the added basic substances in that a quantity of between 3 and 10 % wt. of an acid liquid is added to the fossil fuel, rubbish or the like before the addition of the basic substances.
