Abstract
A coal-fired power station is provided and has a boiler that is heatable by dry firing, a catalytic converter for reducing an NOx level, a flue gas channel that adjoins the boiler and leads to the catalytic converter, and a coarse ash separator disposed upstream of the catalytic converter in a section of the flue gas channel, which includes a sieve that extends essentially over an entire cross-sectional area thereof. The sieve is adapted to be deflected out of a position of rest by a flue gas stream and against the effect of a restoring force, and/or the sieve forms folds that are directed in an upstream direction relative to a flue gas stream and extend essentially parallel to one another.

A coal-fired power station, comprising:
- a boiler 1 heatable by dry firing;
- a catalytic converter 7 for reducing an NOx level;
- a flue gas channel 6 for conducting a flue gas stream, wherein said flue gas channel adjoins the boiler 1 and leads to the catalytic converter 7;
- and
- a coarse ash separator 16 disposed upstream of said catalytic converter 7 in a section 15 of said flue gas channel 6, wherein said coarse ash separator 16 includes a sieve 17 that extends essentially over an entire cross-sectional area of said section of said flue gas channel, and wherein said sieve 17 is adapted to be deflected out of a position of rest by a flue gas stream and against the effect of a restoring force.
