Hello!
I'm going to try and build a quite big boiler. If I remember correctly, it's 4x7.8 inches. The measurements are purely theoretical, as the boiler shell is being riveted together from 4 plates. End caps are going to be copper riveted as well.
Anyway, I decided it's going to have 13 0.4 inch flues, and the boiler itself is going to be a stationary, in some way a Scotch boiler being fired from the wrong side. Just because I don't like real Scotch boilers for some odd reason. It'll function as a pot boiler, but some hot gases will pass through the flues eventually. A steam blower will make that happen. Oh, wood or charcoal fired. Or anything else that burns. Wood and charcoal are preferred though.
Now, for the questions. Some time ago I bought some silver solder, an alloy like L-Ag40Cd. What I'm worried about is the cadmium in it - what precautions should I take? I only got six rods of about 20 inches and they cost a bloody arm and a leg. I can return them as well and get a different alloy, e.g with copper added.
Secondly, about boiler codes. I live in Estonia, it's a small country in Europe, right below Finland. Here, I'd be surprised if even full size boilers get tested in any way. And even if there is something like that, then model boilers are something unknown to the law.
So, should I build the boiler how I like it or should I build it to correspond to a another country's boiler code?
And, what's the max safe pressure to use silicone tubing as a sight glass? I'll change it to glass if I come across some suitable glass tubing.
I shall be putting up my progress here as well. But for now, I have a lot of thinking to do.
Good night,
Timo
