Abstract

For a steam production plant with a flue gas cleaning device, a steam producer is proposed as a single-flue boiler 1 with an upper horizontal gas outlet 2, and with a device for spraying in NH3, a centrifugal dust separator 8, a catalytic nitrogen oxide reactor 5 with dust blowers 5a, and a rotary air preheater 6 with a vertical axis of rotation and adjoined by an electrostatic filter 7 with a horizontal gas passage, arranged in succession in the downward-leading flue 3. The usually empty downward-leading flue is thus optimally used for preliminary dust removal and for elimination of the nitrogen oxides. <IMAGE>
