Arrangement for separating coarse ash out of a flue gas stream

摘要

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.
