Note
I'm experiencing this problem while using the All of Fabric 3 1.16.5 Modpack

Describe the bug
I've built the blast furnace as described and see a successful "Shape Valid" message when viewing the blast furnace. I'm working to make Silicon Dust specifically, which in the case of this modpack utilizes Quartz Dust from Tech Reborn and Coke Dust from MI to create 1 Silicon Dust. I added two Bronze Item Inputs, 1 Bronze Item Output and 1 Bronze Fluid Input for steam. Steam is full and item in/out automation is completely setup, I'm even seeing the 'Silicon Dust 0' within the Item Output as it recognizes the recipe but the blast furnace is still failing to start at all.

Expected behavior
Based on the recipe listed within REI and the prefilled 0 Silicon Dust within the Output Hatch, this should be turning the two input dusts into silicon dust (seemingly after 20 seconds based on the REI recipe screen).

Additional
I'm unsure if this is an MI specific issue or an issue with the Modpack itself, I'll report the issue to the modpack maintainers as well if it's found to not be MI specific (per the AoF3 recommendations)

I've temporarily gotten over this issue myself thanks to AoF3 having KubeJS and creating a new recipe script for the Tech Reborn Industrial Blast Furnace that mimics the MI Blast Furnace recipe but that doesn't really solve the actual issue of the blast furnace not working at all.

This is no bug. Steam Blast furnace can only process recipes with a max of 2/4 EU. Silicon recipe requires 32 EU, you need an electric blast furnace for that.

Many thanks for the detailed report! You do indeed need an Electric Blast Furnace for recipes using more than 4 EU/t. The next AOF update will include a new version of MI that makes this much clearer in REI.

Sorry for the inconvenience, and thanks for the amazing high quality report. :)

@Technici4n @ProjectET Thank you both for the quick responses! Apologies for not noticing the output difference, I let REI confuse me at a glance.
