Abstract

Apparatus for denitrifying power station excess gases (crude gas) which come from a flue gas desulphurisation unit and are heated to the requisite catalyst temperature before the injection of ammonia by heat exchange with the denitrified gases (pure gas) and by supplying additional heat. Known denitrification devices fitted with regenerative heat exchangers operate with large gap and leakage losses, which leads to restrictions in the achievable degree of denitrification and hence the efficiency. Moreover, known denitrification devices have a large space requirement, which makes expensive heat insulation measures necessary due to the free surfaces, in order to prevent a deterioration in efficiency due to heat losses. It is proposed to use, for the heat exchange between crude gas and pure gas, a plate heat exchanger (4) which operates in cross-counterflow, the additional heat being supplied and the ammonia being injected (14) to the outlet duct (9) of the plate heat exchanger. At the end of the outlet duct (9) is arranged a deflection hood (16), with the catalysts (9a, 9b) being arranged between its outlet and the re-entry of the denitrified gases into the plate heat exchanger (4). <IMAGE>
