Abstract: A method generates superheated steam using heat generated in a boiler of an incineration plant. The pre-superheated steam is fed to a final superheater that includes a plurality of final superheater pipes through which the pre-superheated steam is guided and is finally superheated in the process. The final superheater pipes (are arranged at least partially in at least one cavity (formed in an interior of a wall element of the boiler and/or of a bulkhead arranged in the boiler. The cavity is closed off on a boiler side at least partially by a refractory material layer and is flowed over by flue gas released during combustion. A secondary medium flows through the cavity and is heated via heat transfer from the flue gas via the refractory material layer. The heated secondary medium is fed via a secondary medium feed line to a secondary heat exchanger.

Abstract: A method is provided for checking a knocking device which is intended for cleaning a surface of a heat exchanger element arranged on an inside of a boiler housing of a garbage incineration plant. The knocking device has a knocking ram guided through a wall of the boiler housing and movable in a direction toward the inside of the boiler. The heat exchanger element is deflected out of its position of rest into a deflection position by the knocking ram, and the force required for deflecting the heat exchanger element and/or the attenuation behavior of the heat exchanger element released after deflection are/is determined.

Abstract: A filter device for adsorption of gaseous constituents from a gas flow includes a filter chamber with filters arranged therein, a clean-gas chamber connected to the first chamber in a fluid-conducting manner via the filters, and a collection chamber arranged beneath the filter chamber, is open toward the filter chamber and has an interior which narrows toward the bottom. An unfiltered-gas duct which leads from the outside, is arranged in the lower area of the collection chamber in such a manner that it can be adjusted in the direction toward the filters. A dust-discharge device, which leads toward the outside, is arranged in the lower area.

Abstract: A process is provided for removing contaminants, such as nitrogen oxides, out of exhaust gases, such as gases emitted from an incineration plant. Ammonia or a reducing agent producing ammonia is added to the exhaust gases at a point where the exhaust gases are at a temperature ranging from 700 to 900.degree. C. so that ammonia reacts with and removes nitrogen oxides out of the gases; the gases are passed into a boiler where they are cooled to a temperature ranging from 200 to 350.degree. C. and additional ammonia or reducing agent is injected into the gases; the gases are removed from the boiler and alkaline sorbents, such as alkali metal compounds or alkaline earth metal compounds are injected into the gases, and the gases are passed through a catalyst/filter element coated with a catalytically active oxide or salt of vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc, tungsten and molybdenum for catalyzing the reduction of residual nitrogen oxides in the flue gases.
