Good point, I am a NWHS member and will check. I thought the title a bit awkward too but perhaps it was intended to attract an audience?
I was looking for a book deeper than the very general material in my other books. This one, according to the summaries, has some technical details. In past lives I have had to work with pulverized coal and oil fired stationary boilers so I have the basics.
Thanks for the information. Sounds like a roll of the dice!
