Customer case:

A view to better control bed height and shape of the recovery boiler’s smelt bed

Feb 21, 2023

A North American mill did not have a working camera for monitoring bed height and shape, which did not allow operators to monitor black liquor conditions. By installing Valmet Furnace Imaging System, IR, the mill is now able to improve burn efficiency with better black liquor monitoring.
