IMO you'd do better to buy a formal boilet kit such as a PM Research model.
Bob Swinney wrote in message oups.com... Hello, I am looking for plans for a steam boiler. Heat source: 1.5' diameter circle. The boiler has to transfer the heat from this foot and a half circle the best it can into water. I was thinking either 1)a long cylinder, 1.5feet caps on each end. I'd only be heating one end of it though, so I don't know how well it would work. 2) a coil of pipe or tubing, 1.5feet in diameter. Any thoughts, or links (to plans, please) are appreciated. I am also looking for plans for the injector pump, to push water back into the boiler. Rich |

Go for the coil of tubing,The smaller diameter keeps the stresses in the
system lower than for a larger diameter vessel. Pump the water continuously through the coil,into a small separator vessel then back through the coil. Take your steam supply off the top of the separator. Make sure you have a safety valve on the separator. If you plan on using it to drive a CD based Tesla turbine, forget it. The heat will soften the CD's and the whole thing will come unstuck with great vigour! "Robert Swinney" wrote in message ...

Hi,
Thanks for the reply, This is the first I've heard of a "seperator". Do you have links or pics? Also, what is the recommended material for the "boiler coil" ? Recommended method of bending it? Thanks! Rich |

Not that this is an answer to your question, but it is with great
sadness that I learned (a couple of weeks ago) that South Carolina is preparing legislation that will require inspection and licensing of steam boilers. Who wouldda thought that it hadn't been done decades ago! Reminds me of when, about 10 years ago, SC decided to outlaw open alcoholic beverage containers in motor vehicles. After 25 years here, I'm still finding out just how "quaint" this state is... Well, if I ever get a steam engine (I'm serious about wanting one), I'll have to make sure the boiler won't kill me, lest I violate the law.

Who wouldda thought that it hadn't been done decades ago! The inspection and licensing of boiler is one of the bits of government meddling I agree with. Even a small boiler explosion would leave most of the Bagdad firecrackers for dead in terms of energy released. A small boiler exploded in a laundry in Tasmania about 30 years ago and killed about a dozen people. It was a new boiler that had been sealed up for hydrostatic testing. The commissioning engineer got sick and another was sent to replace him. He didn't know that the safety's had gags on them and that the burner control line was blanked off, They believe that it blew at about 5 or 6 times its rated pressure. Ripped the boiler plate about 2 feet from the back end. Didn't go on a weld. They are pretty fussy about oiler here in Aus now. |

Sorry, forgot the separator question.
It's a small vessel that the ends of the coil are connected to. The heat boils the water in the coil, the steam rises to the separator, the steam is taken from the top of the separator and the water continues to circulate through the coil. If you are serious about building this, you'd better do some more research. Its a little more complicated that the usual tea kettle. Designs have evolved since the 1700"so best practice these days is pretty sophisticated. During the industrial revolution in England there was an average of one steam explosion per day until the invention of the dead weight safety valve!

Rich Pick up a couple of old Audel's books, the one for powerplant engineer is good and covers a heap of detail on steam. As with anything, if you go into it with awareness of what can be done, and how, it'll work better and you'll have more fun. John |
