[Steam-engine] Penberty Injector info please

[Richard Strobel]

Thanks Bruce for taking the time.  Looks like we're in pretty good shape 
being given a 100 psi MAWP.  We ran a small stationary boiler last fall, and 
gained some experience in running an injector and staying within the 
envelope.  OJT really paid off here.
  Looking forward to finishing up some small piping projects, get the engine 
and boiler mounted on a skid and we should be ready to go.

Thanks again,
RickinMt.
PS: We ordered our relief valve and fusible from Mike at Stellar.
