COis absorbed from a gas mixture by bringing the gas mixture into contact with an absorbent that comprises water and at least one amine of the formula (I), wherein Rand R, independently of each other, are hydrogen or an alkyl group. According to the invention, absorption media comprise sulfolane or an ionic liquid in addition to water and an amine of the formula (I). A device according to the invention for removing COfrom a gas mixture comprises an absorption unit, a desorption unit, and an absorption medium according to the invention that is conducted in the circuit.

An arrangement for separating coarse ash out of a flue gas stream, comprising a catalytic converter disposed in a widened flue gas channel portion and serving for reducing the NOlevel in the flue gas stream. Also disposed in the widened channel portion is a separator sieve that extends essentially over the entire cross-section thereof. The separator sieve is provided with a plurality of openings for the passage of flue gas therethrough. Each opening has a cross-section that is smaller than a cross-section of coarse ash particles that are to be separated out.

The invention relates to a furnace with a body ( ) of a furnace, at the lower end of which a discharge device ( ) for the ashes produced in the combustion chamber is provided. A continuous conveyor device in the form of a vibrating conveyor ( ) is mounted below the discharge device ( ). The vibrating chute of said vibrating conveyor reliably and effectively removes the dry ashes which are at the same time cooled with air.

In a method for optimizing operation of fossil fuel based power plants, in which the economical effects of the changes of selected operational parameters are determined under consideration of the required economical expenditure, and, based on these additional operational costs, it is determined if, when, and/or what kind of measures should be taken for minimizing the additional operational costs. According to the method, the improvement measures are initiated as a function of the cause of the additional operational costs according to a hierarchal catalog of measures. The measures are: an immediate intervention into the operational course; a later measure implemented during a short shutdown; a later measure implemented during a service shutdown; and/or an operational downtime for a revision.
