This 6x6 factory produces Rocket Fuel at 1200/min without any input resources needed. A port is provided at the back in case you want to use the compacted coal and polymer resin by-products. If not used they will go to sink. The blueprint designer wouldnt let me add a power connector at the front so I have left a gap at each side exposing a power pole. Connect to either.

Thanks to Phosphorium for the inspiration and to randomididot for the miners.

Ideal for feeding 2 of the fuel generator modules designed by x4077 at https://satisfactory-calculator.com/en/blueprints/index/details/id/9686/name/RocketFuelPower.36GW.Stacked
