Yes it is the flash boiler will take what it needs once heated up but I did find with this 1/8" flash boiler water hammer was a problem even with a gravity supply so a simply solution of a ball bearing in a fitting will stop the water hammering. In the trial using the bunsun burner I did find holding the input water tube vertical did stop the hammering and the output shot out a good metre or so.
Yes with all this I'm still learning again as in my younger days steam was the go in my dad;s eyes, we made 6" gauge loco's and won the trials and I asked my dad about flash boilers so I did get a good primer on the subject. The concept of a flash boiler is too do it's job with no pressure or very little so this project will monitor the steam and adapt to suit the application. If the 1/4" output is too small I will increase it and YES I will be putting in pressure gauge to keep tabs on things.
Flash boilers have never become main stream for one good reason........ to stop sheeple using them.
Basically if you don't know what you are doing then don't do it but my fascination with flash boilers spans my lifetime as with the right conditions they just plain work.
