Abstract

The invention relates to an arrangement for the fine distribution of additive in the combustion chamber of a steam boiler for dry flue gas desulfurization. The invention is based on the object, according to the smoke gas density and flue gas velocity add additive in a fixed ratio over the entire combustion chamber depth finely distributed. This is achieved according to the invention in that the conveyor tube (10) is guided in an air tube (13) in the region of the inlet into the combustion chamber (2) and has ring-like cross-sectionally stepped inner tubes (15, 16) and an annular gap (12, 17) ) having tubular chambers, wherein at the common outlet of the air tube (13) and annular gap (12) and at the outlet (18) of the annular gap (17) swirling body (14; 19) and / or perforated chambers are arranged.
