I did steam engines for a while. B&W 650# 840F superheated, modified D-type boiler powering DeLevalle turbines. Burned NSFO but later switched to JP-5.

Also steamed M-type boilers burning NSFO. Modified D was much mo bettah. More responsive and more forgiving, especially on the superheated side.

I always wanted to run a locomotive. Pushing a ship through water was cool, but a big steaming locomotive at 70 or 80 MPH would be a lifetime charmer.

Never steamed a stationary facility. What's the point? Oh wait, I did too. It was a 150# wet steam boiler firing natural gas for cooking chicken parts back into chicken feed.
