Question

Did navies try mechanical stokers on coal-fired ships?

Short answer

Yes. Many navies tested them in the 1920s and 1930s before moving toward oil firing.

Notes

The audience asks whether shipboard boilers ever adopted mechanical stokers. Navies widely experimented with the idea during the 1920s and 1930s. Those trials competed with a broader transition away from coal. Oil ultimately offered better handling, storage, and manpower economics.
