6″ Boiler. First Steaming.
Today I put water in the boiler, about half way up the sight glass, hooked up the gas, and lit the flame. Very nervously. What if it blows up? What if one of the soldered bosses blows out? What if the safety valve does not work?
Admittedly, before that I had pressurised the boiler with water, with the fittings, to 150psi, and without the fittings to 200psi, and that seemed OK except for a leak in the sight glass. But even so, a steam test has a lot more at stake.
I had set the safety valve to 100 psi with water, but steam is a quantum leap in risk.
The burner works OK, but I am expecting that it can be improved.
It took 5 minutes to get to 25psi, 6″ to 50psi, 7″ to 75psi, and 9″ to 100psi. At that point the pop safety valve released, suddenly and loudly, giving me quite a start. For a few psi under 100psi it had been releasing small amounts of steam, but the “pop”, in the confines of my workshop, was really impressive.
And a video of the boiler at 100psi. Sorry about the commentary. Must brush up on my video skills.
I’ve been been preparing for hurricane Lane for the past few days. It’s a lot more fun to see you light up. The gauge is right handsome, I couldn’t imagine another.
I wonder how long it will take to fire up with solid fuel. Will you be testing that next?
I also have thoughts and questions about your propane burner, but I’ll have articulate them later. Storm at hand.
Good luck Richard! I will get the boiler going properly on gas first. Then to try coal. Any advice re propane will be welcome. I am constantly aware of my ignorance on these new areas of knowledge.
Very impressive John.
Appreciate the feedback. Thank you.
Very nice work. The video is really cool.
Thank you. I appreciate the feedback.
