摘要： In a method of incinerating waste material in a parallel flow process wherein hot exhaust gases are conducted above a combustion chamber grate in the same direction as the material is moved on the grate, different temperatures zones are maintained to which air is admitted from the bottom through the grate such that a temperature of less than 900.degree. C. is maintained in a first zone which is a drying zone, a temperature of about 1000.degree. C. is maintained in a second zone which is an evaporization and vaporizing zone, a temperature of about 900.degree. C. is maintained to in a third zone, which is the final combustion zone and a temperature less than 900.degree. C. is maintained in a fourth zone which is a sintering zone. Additional air is supplied to the combustion zones 1 through the side walls of the combustion chamber. A dividing wall is disposed above the grate over which the hot combustion gases are conducted to a discharge opening so that heat is transferred to the dividing wall for radiation back onto the waste material on the grate.

摘要： Improved flue gas purification process features a heavy metal separating process, such as an anion exchange process, in which a scrubbing condensate is treated to remove at least the Hg contained therein prior to extracting the flue ash, which was previously separated and collected, with the scrubbing condensate to extract soluble heavy metals therefrom. A further heavy metal separating process, such as a cation exchange process, in which the scrubbing condensate after the extraction step is treated to remove at least one of Cd and Zn contained therein is also featured and may be performed after the extraction step or after solid/liquid separation of the flue ash and condensate from the extraction step.

摘要： A process for the purification of flue gas generated during the combustion of waste materials has a first embodiment wherein soluble heavy metals are precipitated and recovered in a compact form and wherein the soluble heavy metal-free extraction residue is returned to the combustion system where noxious organic substances are pyrolyzed. In another embodiment, substantially all of the heavy metals from the flue gas are collected in a single solid residue, which residue may be thermally treated to recover mercury and the treated residues subsequently returned to the combustion system wherein noxious organic substances are pyrolyzed or combined in a hazardous waste stabilizing substance. In yet another embodiment of the process, heavy metals present in an acidic condensate solution from a condensation/scrubbing step are precipitated and the precipitated heavy metals are thermally treated, together with the flue ash, to remove mercury, after which the remaining solids may be returned to the combustion system to pyrolyze noxious organic substances contained therein or may be combined with a hazardous waste stabilization substance.

摘要： In a method for the continuous surveillance of the poison content of exhaust gases containing particulate material such as exhaust gases of large furnaces or waste incinerators, a sampling stream is continuously drawn from the exhaust gas stream through a suction line at a rate which corresponds to the exhaust gas stream flow rate, the sampling gas stream is passed through a cyclone in which any coarse particulate material is removed from and collected in a storage container, whereupon the sampling gas stream is passed through fine filter units in which fine particles are removed, a partial gas stream drawn from the particle free sample gas is passed through washing columns in which poisonous gases are washed out of the gas and dissolved in the washing liquid and from an analysis of the coarse and fine particulate material and the washing liquid, a poison distribution standard is determined whereupon for a period of time only coarse particulate material is collected and the poison content of the exhaust gas is then determined therefrom on the basis of the poison distribution standard.

摘要： The present invention relates to a process for purifying flue gases developed during the combustion of waste materials and containing solids of various compositions as well as pollutant gases and heavy metals in gaseous form, wherein the primarily solid components are removed from the flue gas in a separating system and are collected as flue ashes and wherein the flue gas is washed for the purpose of binding the pollutant gases of the residual solids components, particularly in the slag.It is the object of the present invention to provide a process wherein, during flue gas purification, the gaseous heavy metal contaminants as well as the heavy metal contaminants which are present in the flue ash and in the slag in soluble form, can be removed from the flue gas purification process in the most compact form, with simultaneously achieving good, or even improved, initial purification of HCl, SO.sub.2. NO.sub.x. All other residues should be returnable for further use. The remainder of heavy metal components which are not bound in the slag are isolated from the slag by a subsequent weakly acid treatment.
