so a good steam generator would have a coil around the exhaust manifold that heats water in a pressure cook type container with 2 release valves, 1 that releases the steam into the intake for combustion when it reaches the right pressure (what ever that might be, have to see that steam table) for the right "quality". and the second to release the over pressure to maintain the correct "quality"? sound right? simple enough if so. This is one of the tests Im wanting to try on my small power generator.
