Riskullaverket, Mölndal Sweden

Application: Biomass boiler

Product: HISS

Situation description

The boiler at Riskullaverket was originally built for 70 MW but Metso had prepared it for additional power load, so the load is now 80 MW. There are 8 retractable sootblowers in the superheaters (Clyde Bergemann, 6880 mm) and 11 sootblowers in CONV/ECO/APH.

Before HISS was installed, soot blowing was employed twice per day and each soot blowing cycle meant 1 MW decrease on turbine load for 2.5 h (duration of one soot blowing cycle).
