Aug 09, 2018 · One client, a paper mill in South Carolina, came to us in December 2017 with a pressing need: they were experiencing serious problems with their recovery boiler and supporting equipment like the precipitator inlet and outlet, ductwork, expansion joints, and isolation dampers. There were several problems at hand.
boiler, whereby the recovery boiler serves as a steam boiler. On the other hand, the chemicals from pulp digesting - sulphur and sodium - are recovered from the black liquor, the recovery boiler then serving as a chemical reactor. This double function makes the design of a recovery boiler rather complex and the operation of such a boiler much
ANDRITZ (former Ahlström) delivered its first kraft recovery boiler in 1952 to Lohja mill in Finland /4/. The capacity of this boiler was 110 tds/d and steam production 5.0 kg/s (18 tons/h).
