A brand new biomass CHP plant in Washington state, US is expected to be offline for several more weeks following the discovery of multiple cracks in the boiler’s giant water-containment vessel.

The Peninsula News reports that Nippon Paper Industries USA‘s new $85m biomass cogeneration plant is currently out of commission with mill manager Steve Johnson not yet able to provide a re-activation date.

The cracks at Nippon’s plant have compromised the new boiler’s mud drum, a forged steel component that holds water and is about 45 feet long and 36 inches in diameter. It is one of two boiler drums connected by 1,500 pieces of piping.

Mr Johnson did not know the source of the cracks, but he said the leading theory is caustic water combined with high temperature who also predicted the amount required to pay for repairs will be significant.

Johnson said he did not know if Nippon or Covington, LA.-based Factory Sales & Engineering, the primary contractor of the boiler, would pay to address the problem.

The cogeneration plant, which had a price tag that grew from $71 million to $85 million, was dedicated in November.
