There is an interesting article in the latest AME on "Rosebud" fire grates
something that I hadn't heard of before. the author Les Phillips wasn't sure
where they originated. ( maybe somebody can enlighten me) they look to be
simple to make just a flat plate with drilled holes chamfered on the underside.
Les's experiments burning char show that an air space to solid ratio of 10% is
best, that was after working his way down from 50% which is usually
recommended for coal.
Has anyone any knowledge of these grates, good or bad.
