Recovery Boiler House, Walthers 933-3901
This set from Walthers Cornerstone recreates a waste recovery boiler, which is a key element of a paper mill.
During the papermaking process, a fibre and water solution known as brown stock is concentrated in the recycling boiler through evaporation to form black liquor. This substance is further processed to produce resin and other chemical products, and the residue is burned to generate steam and energy for the entire mill.
The boiler room also allows for the recovery of other chemicals for reuse in the papermaking process.
Dimensions of the assembled model: 29.8 x 20.3 x 43.1 cm.
