I remember reading that some coal-carrying bulk cargo ships were being built -- or at least proposed -- with coal-fired steam plants (probably turbines, not triple expansion or uniflow engines) into the late 1970s.
Of course, coal-burning diesel and gas turbine engines were (are?) an active area of R&D. I believe Sulzer had some test low-speed engines burning powdered coal, and I believe GE had some gas turbines doing so. I think the latter were given up on as the coal ash pretty quickly destroyed the hot end.
This is not a signature.

The oddest ships I can think of that fit your criteria would probably be the Ferris design 1001 wooden hull freighters contracted under the United States Shipping Board and the Emergency Fleet Corporation during WW-1.

Very interesting, I've never heard of these ships before, thanks!
