How can anyone who knows anything about steam engines be that dumb?Prat isn't the word I would use now, more likely the word for a loop formed by separating one strand of a rope during splicing, or perhaps the gap between three barrels in a stack.
I went to sort out the injectors on a very nice private Edwardian launch on the Thames a while back, the boiler wasn't filling, so the owner was having to use the hand pump constantly and was considering having a pump on the prop. shaft.
I was at a complete loss as to what was up, had the injectors apart, cleaned them, checked the pipes all OK. Then I filled the boiler and lit up. The pressure built up nicely, too nicely, the gauge soon showed 300 psi and then was against the stop, on a boiler certified for 120, but not a wisp of steam from the safety valves! In effect we were sitting next to a bomb. Fire out just in time and I asked the owner if anyone else had looked at it. It turns out that our "guru" had been to see her about a fortnight previously and suggested that a higher pressure would "squirt" the water into the boiler better so it would be a good idea to screw the safety valves down solid!
My gast is utterly flabbered!
