Balancing steam supply with demand saves energy

Steam availability is maintained by regulating balance of the steam network by ensuring that boiler production matches consumption from the turbo-generators and mill processes demanding process steam at any instant. Most steam at the mill is produced by three recovery boilers, with the balance from two power boilers burning biofuel.
