Situation description
The Customer has a 16MWth biomass furnace with a hot water smoke tube boiler and subsequent economizer in Heby, Sweden. Their focus is mainly on delivery to all lumber dryers, and the facilities on the sawmill area.
The Customer had a different automatic cleaning system installed, which they were not satisfied with. The tubes in the boiler and the economizer were earlier cleaned manually when the flue gas outlet temperature was over 200 degrees. Also, the multi-cyclone suffered from fouling with time.
