Mostly just doing it for fun. Some people try bases where they mostly use bots, or mostly use trains, etc. I've just taking a liking to burner inserters of late, and trying to see if I can come up with some "good" furnace layouts, or "good" science builds using only burners has b...

Mixing the coal and ore on the same belt meant .... Why your not simplifying matter by using a electric furnace? I would still need the coal to feed the burner inserter itself. Changing the furnace type doesn't fully address the problem; would reduce the required actions of the loading inserters, b...

Mixing the coal and ore on the same belt meant that the belt ran down too fast: burner inserters have a hard time grabbing from red belts, spending a lot of their time trying to grab an item as it goes past, and a yellow belt with half ore and half coal can only sustain ~10 furnaces (if I recall cor...

I've been playing with burner inserters recently. Trying to work around the coal requirement has been tricky, but I worked out a decent smelting setup. One input inserter couldn't keep up with the furnace's demands for both ore and coal, and two inserters meant that the belt couldn't keep up. I don'...
