Stainless is a very poor choice of boiler material. The chemistry inside a boiler causes some of the alloying metal in the stainless to break down and eventually you have a porous boiler. I don't know where to find this info, but it is well documented. I'm only informed on it as I had a steam car with a stainless boiler and was made well-aware of it's shortcomings!
Modern boiler packages are not always what is needed on "antique" steam equipment that has a much different variable steam demand than modern stationary steam plants. This is why I worry when I hear of installing package steam plants in our historic boats. The over design to extremes that the DQ & DK had in their boilers served the DQ very well! I realize the over design was due to a fluke, but what a blessing it has been!
