A Stuart Twin Launch Steam Plant
This Stuart Turner vertical steam engine has 2x1 inch bore cylinders & needs a very good supply of steam to run properly. The gas fired boiler had to have a very powerful fierce gas burner to keep up with the steam consumption & subsequent cold water inlet feed when running. I found that the Stuart Turner boiler feed pump was very wasteful in the way it consumed steam relative to the small quantity of water that it pumped on each stroke.
