Object description

The steel furnace is the second tier of furnace. Compared to the stone furnace, it smelts at double the speed and is therefore a more efficient use of the given fuel, but emits twice as much pollution. Compared to the electric furnace, the steel furnace is smaller, smelts items at the same speed by default and smelting consumes 90kW in fuel as opposed to the electric furnace's 180kW in electricity. However, the electric furnace requires no fuel other than electricity, emits only a quarter as much pollution and is the only furnace type with module slots, allowing it to benefit from speed, efficiency and other effects.

Placement

A steel furnace can replace a stone furnace without mining the stone furnace first. This can be done by clicking on the stone furnace with the steel furnace in the players hand. This will also move all items in the stone furnace to the new furnace.

Steel furnaces, like all burner devices, cannot be placed in space.
