Low emission operation of automatic wood boilers operated in cascades

Feb 2023

This report concerns installation of cascades of three or more usually identical serial devices of smaller wood boilers as an alternative to industrial boilers, and how their operation affects emissions.

Cascades of smaller boilers can be used where space is more limited, and they will allow for production to be less affected by periodic maintenance, as not all boilers will need to be shut down for this. Conversely, they allow for variation in the total heat production in a wide load range, e.g., by operation of one single boiler during the summer period.

The report is based on a research study carried out in Switzerland.
