The failure of a recovery boiler at Canfor Pulp Products’ Northwood mill has led to the shutdown of one production line at the mill.

The failure of a recovery boiler at Canfor Pulp Products’ Northwood mill has led to the shutdown of one production line at the mill.

There were no injuries reported from the incident, but the number one recovery boiler has been shut down to determine the cause of the malfunction. As a result, only one of the two production lines in the mill is currently operating.

According to a local news source, HQPrinceGeorge.com, the malfunction was caused by a chunk of residue called a “clinker”, which dropped in the boiler and broke several screen tubes. Water then made its way into the boiler and caused reactions.

Based on a preliminary review, Canfor estimates the curtailment will be for at least three weeks with an estimated reduction in production of NBSK pulp of approximately 25,000 tonnes.

To mitigate the impact of the incident, the company intends to continue operation of the second production line at the mill and will advance certain mill maintenance activities previously scheduled to be performed during a planned mill shutdown in September. Production at Canfor’s Intercontinental Pulp Mill and Prince George Pulp and Paper Mill is not affected by the curtailment at Northwood.
