i'm making a boiler can i use a one way valve? Answered
so i'm trying to make a boiler system so that i can get a little bit of energy back from my forge the idea for the forge is to basically cut open a 55 gallon drum on the bottom flat side and put a forced air pipe in the small orifice normally used as an air hole when dumping the barrel. then i'd cut out the space needed to fit 4 inch stove piping where the larger 2 inch orifice is and carry the exhaust outside and out of mind. then i'd cut a hole in the bottom of the barrel so i can get my work in, put in a steel plate that was cannibalized and drill a few air holes in it, put refractory cement everywhere and bob's your uncle.
what i want to do however is to put some water pipe in the fire box and have it turn a turbine or something, i'll cross that particular bridge when i get to it. but the main question is how can i safely store a reservoir of water so that the pipes don't run out of water halfway through a burn cycle? the thought was that i'd invert another 55 gallon barrel and connect it to one end of the pipes with a one way valve. the only question is would the valve guard the second barrel from the pressure generated while still allowing the water to flow in when necessary? or would the barrel just load up with pressure and when i hit 20 psi it just explodes in a hot watery mess?
any knowledge about this would be great, stuff like where to get cheap but good pipe in upstate new york, where to get regulators, how to find the valve itself, or even where i can find safety fittings like pressure release valves and temperature control.
