Blue Belt to Furnace Ratio

Postby Tias »

I could never find the perfect Blue Belt/Elsectric Furnace ratio, so I tested it.
It requires 61 Electric/Steal Furnaces (or 122 Stone Furnaces), to completly smelt all the ore on a completly saturated blue belt.

thanks Blue Belt to Furnace Ratio (3)

so 30 on each side? or a length of 61 with furnaces on both sides? but taht would make a lot of furnaces Blue Belt to Furnace Ratio (4)

it's actually more, you need about 72 of steel/electric furnaces

maybe you had the furnace buffer full

Gleaning the wiki, it's learned that a blue belt can transport 40 items per second (throughput, T).
Knowing that it takes 1.75 seconds for an electrical or steel furnace to process a piece of ore, we get 1/1.75 ore per second per furnace (production, P).
To process 40 ore per second, you would need 70 (= T/P) furnaces.

Going by dimensional analysis, this approach should be correct.

It does not matter how the furnaces are arranged.

If you are only getting 61 you probably have a bottle neck somewhere in your system or are not compressing the blue belt.

I usually build 72, but technically 71 should be mathematically enough/correct.

I found that when I put the iron plates directly from the furnaces to the blue belt, the inserters would space them out a bit too much and the result would be the final furnaces near the iron output end are unable to unload properly. 36-48 is the max if you're using blue/green inserters directly onto the blue belt. Otherwise you're going to have to find a way to compress the iron as it comes onto the blue belt.

this is only way I know of (36 furnaces on each side should compress it, if you can keep the ore coming)

I'm not sure what the numbers are if you put PM3s on the furnaces and SM3s in bacons in rows beside the furnaces - presumably less than 36 on each side, but I don't know how much less.

Is there a reason the inserters are not directly putting them into the splitters?

Probably not, I just don't personally like pointing inserters at/against turns, splitters, or undergrounds entrances/exits; but I think that's just an aesthetic preference. (I could be wrong, though - there might be a real difference)

Blue Belt to Furnace Ratio (2024)

FAQs

What is the ratio of furnace to blue belt? ›

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: Pretty simple right?

How many furnaces to saturate a belt? ›

24 stone furnaces are enough to fill half a yellow belt with iron plates. So to saturate the belt, 24 stone furnaces each side.

How many furnaces does it take to fill a belt Factorio? ›

Re: Confused over ore-to-plates ratio

For Steel Furnaces (craft speed 2) you need 24/48/72 furnaces to turn a full belt of ore into a full belt of plate. Electric Furnaces are really there for when you are going to start using modules and beacons.

What is the best smelting setup in Factorio? ›

The way to go is to establish two furnace columns facing each other's back (stone or steel) with a tile gap for expansion for every furnace. Later in the game, the gap would be helpful for an electric furnace upgrade (3x3 tile).

How many make it to blue belt? ›

As I have heard different black belts say, not more than 10–15% of the jiu-jitsu practitioners get to a blue belt level. If you do, bravo. But sadly, most people quit after getting a blue belt. Only about 3% of the practitioners reach the purple belt.

How do I know if my furnace belt is bad? ›

When you are hear loud hissing or squealing sounds coming from your furnace, this is a sign of a loose fan belt. Old, worn out, and overstressed fan belts can also cause a rubbery, burning smell. If this is the case, turn off your system and call a professional technician right away.

What is the drill ratio for Factorio furnace? ›

Ratio is 2 furnaces to 1 drill. So 8 furnaces would stop the ore from backing up with 4 drills.

How many miners does it take to saturate a blue belt Factorio? ›

If it takes 27 drills to saturate a belt, few people will bother concocting a way to have that odd-drill-out alternate belt lanes.

What is the throughput of the blue belt in Factorio? ›

Some numbers to keep in mind, a yellow belt is capable of transporting 15 items per second (7.5 per side), red belts are twice that (30 per second) and blue belts are three times that (45 per second).

What is the optimal boiler ratio Factorio? ›

The current optimal ratio is 1 offshore pump to 20 boilers to 40 steam engines. Using steam engines for power does not produce pollution, however using boilers to heat up the water does.

What is the best oil ratio Factorio? ›

For producing petroleum gas, the optimal advanced oil processing ratio is 20:5:17 (advanced oil processing : heavy oil cracking : light oil cracking), and 8:2:7 is close enough. Using coal liquefaction, the ratio is 60:39:55 (coal liquefaction : heavy oil cracking : light oil cracking), and 12:8:11 is close enough.

What is the air fuel ratio for a furnace? ›

A furnace operates at 2,400° F flue gas temperature. The optimum ratio is 10% excess air (2.1% O2 in flue gases), but tests show an actual ratio of 25% excess air (4.5% O2 in flue gases).

How many drills does it take to fill a blue belt? ›

If it takes 27 drills to saturate a belt, few people will bother concocting a way to have that odd-drill-out alternate belt lanes.

What is the replacement ratio in a blast furnace? ›

An index widely used in the blast furnace operator is the replacement rate (RR) defined as the amount of co*ke saved (kg / t hot metal) for each kg of coal injected by ton of hot metal.

What is the ratio of air required for complete combustion? ›

It is released as heat. It is seen that 4.76 moles (1 mole of oxygen and 3.76 moles of nitrogen) of air are needed for the theoretical combustion of 1 mole of carbon.
