TRANSCRIPT
Principles.
● Cooling of the gases from direct furnace evacuation by injection of atomised water into water spray chamber.
● Variable regulation of the injected water amount main-taining the outlet temperature of the HTQ below the temperature level of the dioxin/furan de-novo-synthesis and protecting the bag house against peak temperatures.
● Increase of dedusting system efficiency by reducing the DEC system offgas volume and dust load on the filter.
Concept.
● Atomising of the water by nitrogen or compressed air in spray lances.
● Supply of water and air/ni-trogen controlled automatically by a state-of-the-art valve rack.
● Water amount correlating with the process stage/offgas temperature providing a full evaporation of the water in the spray chamber, even at low temperatures.
● Dust removal at the bottom of the spray chamber tower by front-end loader.
Advantages.
● Lower pressure drop in theDEC duct.
● Less water-cooled duct surface area required.
● Less dust deposit in the ducts.
● Elimination of tubular cooler and booster fans.
● Better bag house utilisation by reduced and stable temperature.
● Economical solution for dioxin and furan reduction.
● Quick and easy maintenance.
● Low operating costs.
