Ahlström-Munksjö Aspa Bruk, Aspabruk Sweden

Application: Recovery boiler

Product: HISS

Situation description

The goal with the HISS project  at Ahlström-Munksjö Aspa Bruk was to run the boiler at maximum load and increase the cleaning effect in the boiler with maintained steam consumption. The problems with plugging in the Superheater and the Boiler Bank created a need for frequent explosion cleaning. HISS was installed with the intention to reduce the need for explosion cleaning and to reduce the number of stops for water washing. The boiler initially used 24 sootblowers but added a 25th sootblower in 2017 to increase the cleaning effect further.
