I have a lot of unwanted coal dust. How to remove / void it ?

It cant be burned to ash.

Use it for all smelting etc. After that I don't think there's an alternative to dumping it before blue science

Make it into silicon before blue science. Or you can burn it to ash in High pressure furnace.

You cant turn fuel into ash. The game didnt allow it.

There's a recipe that turns coal dust to ash, but it doesn't unlock until much later.

Before you get diamond processing unlocked (presuming you're running the full or full-ish suite) your options are basically smelt/boiler fuel, silicon, charcoal briquettes, and tossing them into warehouses. None are particularly great options:

smelter/boiler fuel:

steam engines usually lose out to combustion turbines, and for it to be reliable, it needs a steady stream of another fuel type
the highest volume smelting processes get forced over to coke fairly early in the rawore processing stages

silicon:

mostly delays the problem, as the use for it won't kick in until you're working on circuit 2 ingredients, and that will end up bottlenecked on other things

briquettes:

you can't use them for anything but raw boiler/smelt fuel until much much later, and the glycerol to make them will need a fair amount of nichrome to make oleochemicals

warehouses:

it will fill up eventually

The good news is that once you unlock the coal dust -> kimberlite recipe with the basic diamond processing tech, that can serve as an effectively bottomless pit

That's a nice reply, reapersms. It would be a shame if someone were to make it obsolute almost immediately.

Sheesh. Where was that recipe 100+ hours ago...

Not that it would kick in since I'm still on the 0.16 versions, but that of course shows up just after I get a coal processing setup dedicated to syngas going...

Huzzah!

Hmm. I see the recipe in FNEI but its not available in the gasifier. How do I get this to unlock?

I'm such a newb.

Try this console command
