[0.15.35] Boiler type entities cannot eject burnt items

We are aware of them, but they have low priority. We have more important things to do. They go here in order not to take space in the main bug thread list.

[0.15.35] Boiler type entities cannot eject burnt items

Post by Hexicube »

The burnt item slot on boiler entities cannot be emptied via inserters, which results in such a boiler eventually backing up and stopping entirely since no other method for automating this currently exists. Fuel items provided to the boiler can still be extracted via inserters.

A mod is attached which recreates the issue by setting the vanilla boiler fuel category to nuclear, as well as massively dropping the efficiency so that it consumes cells at a reasonable rate, and adding a burnt item slot.

Thanks for the report. This is unfortunately a limitation of the game as it is currently. An entity can't have 2 output inventories that inserters will grab from meaning the boiler which already has the main fuel as output can't also have the burnt result output.
If you want to get ahold of me I'm almost always on Discord.

Which is kinda meh, because it makes the nuclear burner type broken, if you base it of the functionality the reactor has. :/

I've yet to see an effective design for 0.15 boilers that uses the fuel sharing mechanic, surely that could be removed? It feels like a relic of the old boilers more than anything since the new boilers use 3 of their 4 sides for fluids.

While i myself wouldn't mind if inventory-chaining in general would be removed (boilers, labs), i did use it on my last map:

I also wouldn't mind if the inventory-chaining would get removed if it would enable modders to take advantage of ejecting something like burnt items into the output slot of Boilers etc.

Inventory chaining used to be interesting when you needed a shit-ton of the old 1x1 boilers and even then I never really used it because I always use burner inserters for my boilers (to prevent power-death spirals) and they are only more fuel efficient against electric inserters if they don't have to move a lot.

Effective, no, but I've seen two: one that's been demonstrated, and two rows of boilers offset so the fuel zigzags between them via inserters.

Is it possible to make output inventory selectable instead of hardcoded, so that modders can create a copy of the boiler that outputs waste and cannot share fuel? Alternately, them having single inventory that whitelists fuel items only, so that inserters can both insert fuel and take out waste, but nothing else.

Vanilla fuel leeching via inventory chaining is still good for some medium-scale pre-nuclear power plants:

And with mods you can even get all-burner smelting setups including ore-to-steel double columns:
