  • Patent number: 8062600
    Abstract: 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 NOx level 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.

  • Patent number: 6230495
    Abstract: 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.
