When the Steam Doesn't Stay in the Tube: Day 2
Here are a few more pictures.
As of last night they had removed 16 tubes. Two tubes were blown out, and three had some holes worn in them, the other 11 tubes were cut out just to get access to the tubes in the bundle.
Here you can see the two blown tubes, one bent to the right, one to the left. We are still trying to determine what was the original cause of the failure.
And a close up of the two blow tubes after they have been cut from the bundle.
The tubes in this section of the boiler are 2.0" dia. and have a wall thickness of about 0.203". And they are all bound together. So, to have them open up like this, and get bent as badly as they did shows the tremendous force involved in life steam.
