Barrett Lives - steam car boiler stabilises at 1500 psi

So the steam generator's essentially like that of the later Doble steamers? Now that's classy

[rtdgreg]

@AngryVGFur yes, very similar. Tubing is stainess finned tubing - half inch outside diameter. I think Doble uses soft iron, about one inch OD, but much thicker side wall.

The fin tube gives a much greater surface area per unit volume. Barrett gets a 300 kilowatt heat exchanger into about one cubic foot. Doble gets an 800 kilowatt heat exchanger into about ten.

There's quite a lot of anecdotal evidence that stainless is not such good material - tends to pin hole leaks springing out.

What''s the type of your boiler?

[rtdgreg]

Some would argue it's not a boiler, it is a steam generator. It is of monotube construction, consisting of about ten layers of spiral pancake coils. The lower ones are 10mm, the upper ones are 12mm fintube - the fins reaching out to 25mm. All stainless steel. Total enclosed volume - about a litre. Fire is at the top. Down draft exhaust gases - driven by electric blower. Water enters at the bottom. Steam delivered at the top.

Nice vid! The on-screen comments are a good touch. It looks like you started the fuel supply at around 0:20 and began steaming at 1:20, so you've got pressure after about one minute? Was the water pre-heated, or did you use a pilot light of some kind?

i just read the title does this mean you

did not build i thought you were mr barret

eather way great vid and thanks for the responce to my comment

very cool set up i live for complex set ups like this and 1500psi wow ,,your a brave man how many inches thick is that boiler

,lol ,you probly have a tube system for pressure that high despite the apperance

of the tank ,nice work it must be like operating a space ship or flying a harier jumpjet lol, im not nocking your work

im refuring to the complexity of the controls of a set up like that,,, i love it ,,,
