Any ideas how to keep a steam boiler full of charcoal. I have a tree farm set up and furnaces making the charcoal. How do i go about keeping them from exploding.
For on-demand low-end power, after you get through your initial phase of 'a couple of hobbyist engines to get yourself started', I like to go Magmatic. It's fairly easy to set up once you hit the Nether, the biggest expense involved are, in my opinion, the enderpearls at that stage of the game (before you actually hit the End) for the liquid tesseracts.If the boiler is already at full heat, you only need to put a powered furnace next to it that has a steady supply of logs. What I have in my setup is two powered furnaces in between two HP boilers. An Aqueous Accumulator is more than enough for either type of boiler.
But yeah, a powered furnace by itself is enough to run a single boiler that's at full temperature. If you're not running it 24/7, then you might want to just consider using hobbyist's steam engines, regular TE steam engines.
