The invention relates to a system for controlling the flow field in a soda recovery boiler, said soda recovery boiler comprising at least a furnace ( 1 ), primary air ports ( 4 ) in the lower part of the furnace, so-called secondary combustion air ports ( 5 ) disposed above these, black liquor spray nozzles ( 6 ) placed similiarly above these and combustion air ports ( 5 b) disposed above the black liquor spray nozzles ( 6 ). According to the invention, the soda recovery boiler is provided with substantially thin jets ( 7, 7 a, 7 b) supplying energy into the flow field and having a jet pressure in the nozzle equal to at least twice the jet pressure in the combustion air ports ( 5, 5 b). |
