Abstract (en)
The invention relates to a method and an arrangement for adjusting the operation of a dissolver of a recovery boiler. In the invention, green liquor generated in the dissolver (2) is applied to a separate vent gas scrubber cooler (4), to which vent gas generated in the dissolver (2) is simultaneously applied for washing. The vent gas scrubber cooler comprises a separate condenser (5), onto whose surface the green liquor is sprayed. Water is applied through the condensers (5) and it cools the green liquor and, when heated, is applied to further use. At least part of the cooled green liquor is returned to the green liquor tank (2). <IMAGE>
