KETO specialised field service engineers attend site to repair damaged turbine housing
A borax mine located in Boron, California home to the largest open-pit mine and borax mine in the world, produces nearly half the world’s borates. An annual overhaul maintenance inspection was scheduled on site for a power generation turbine housing.
KETO field engineers were consulted and attended the mine site to evaluate the repair of a turbine housing. After inspection it was identified that there was damage to a flange which had a washed out counter bore on the emission system that needed to be repaired. The component that is placed into the counter bore is part of a burner nozzle emission system and if not repaired would cause non-compliant operation of the turbine.
Due to the scale of the turbine housing, repairs were required to be conducted in place as the one piece casing was too large to move off-site for repair.
The repair had to be conducted during a scheduled shutdown to avoid costly energy curtailment fines. It would also leave the plant without steam, requiring them to fire up their boilers which are very inefficient compared to turbine co-generation.
