I have been trying to research where, when and how the standard for boiler construction changed from 10 square foot per BHP to 5 square foot per 10. I have books from the 1920s that have information and calculation on the 10 sq. ft and know that sometime in the 1950's the standard changed but can't find any facts as to why, when or who decided upon the cahnge. Any infiormation anyone can give me or an idea of other books to refer to would be appreciated.
