Daniel Fraser steam boiler

Boiler drawings
This boiler was produced in 1836 at Motala Verkstad, Sweden for the Paddle Steamer Eric Nordevall. These boilers didn't have tubes, but plate-ducts for the exhaust gases to pass through the water space.
Not the three try-cocks, to check the water level in the boiler.

Paddle Steamer Eric Nordevall II
The replica of the steam boiler is almost ready for the pressure test.

Notice that the boilers level gauge glass is mounted higher up than the try cocks on the boiler drawing. This gives a very small steam space and it might cause Carry-Over.
