4 stroke lawn mower converted to steam, fabricating boiler
bj:
You have put a lot of thought into it, and it looks pretty good. Only thing that comes to mind
is to make sure your PSV (overpressure valve) is big enough.
Well done.

Hi, from the information that is a available all the parts for the pumping is rated at about max 500 psi. The system is small and I am keeping the fire really small until I understand how the system works. The article show what happens if there is a system failure. The over pressure valve is set to trigger at 110 psi. If the OPV ever triggers I will open the output bypass valve to quickly release all the pressure. Safety is always a real concern.

Hi, completed the vawt project and after testing last winter I realized that live in a low wind area. 99.9% of the time the wind speed for my area is below 8 mph. So I started the steam project. What I learned from the vawt project, PMA and MPPT info will be applied to steam project. No or low wind, No power. :'(
I am converting a small air compress pump to work as a water feed pump for the boiler. I will post results when available.

boiler modifications: added steam drum, using air compressor pump as fresh water feed pump
hope to test in a few days then I can start to insulate

Hi, I used JB weld epoxy to fabricate the additional lowbs on the cam of the 4 stroke. It did not last long, I was able to scrape it off with my finger nail. It just can't take the heat. I have to refabricate the additional lowbs. It was a good learning experience.
