  • A yellow belt can handle up to 6.6 items/second/lane if they are compressed. So you can use up to 23 furnaces to fully saturate a yellow lane. The problem is: the items will not placed compressed on the lane, so my solution is to use partly red belts where the plates are placed.

I think I worked it out as something like 22/23 for a standard belt of ore. I generally just go with 20 because compression is a thing.

Inserter compression varies widely, anything between 60% (7 furnaces on a yellow belt) and 80% (9 furnaces on a yellow belt) is possible. You can try stopping the belt or clearing the belt to reset the item pattern and get a different result.

So the ideal ratios between furnaces and transport belts are as follows: Regular Transport Belt: Stone - 46.6755 (Rounded to 48) Steel/Base Electric - 23.43775 (Rounded to 24) Electric with speed 3 - 11.718875 (Rounded to 12) Fast Transport Belt: Stone - 93.751 (Rounded to 94)

48 stone furnaces (crafting speed 1) per yellow belt (15 items/s). Multiple the number of furnaces by 2 for red or 3 for blue belts, and cut it in half for moving to steel or electric without modules/beacons. 1 level 2

Using Stone Furnaces, and for smelting Copper, Iron, and Stone you need 48 (24 per side) to completely saturate a Yellow Belt, 96 (48 per side) for a Red Belt, and 140 (70 per side) for a Blue Belt:

How many items per second that are moved from one tile to the next. That is density (items per tile) multiplied by speed (tiles per second), e.g. for a basic belt it is 4 * 1.875 = 7.5 items per second, for one belt lane. For both lanes it is doubled, i.e. 15 items per second. Compression.

One yellow belt of coal can feed 666 furnaces! That's almost 14 arrays! However, a full belt of iron or copper is required on the other side. Time to put in the inserters!
