Electric Blast Furnace (GregTech 5)

The Electric Blast Furnace, or EBF, is an industrial evolution of the conventional Furnace. It is a 3x3x4 multiblock construct, powered by electricity (EU), and allows for the smelting of more advanced materials than the Furnace.



There are two limitations on what materials an Electric Blast Furnace can smelt: Voltage and Heat Capacity. Both are determined by the structure of the EBF. Voltage is determined by the tier and number of Energy Hatches used. Heat Capacity is determined by what Heating Coils were used.

Construction
The Electric Blast Furnace is a 4-block high hollow 3x3 box. The top layer is constructed from 8 Heat Proof Machine Casings around one Muffler Hatch. The Muffler Hatch must be facing up and must be facing an air block.

The two hollow middle layers are constructed from 16 Heating Coils.

The bottom layer is more mixed, and must contain the following: The bottom layer may also contain 1 Input Hatch, used to input fluid Oxygen gas for some recipes.
 * 1 Electric Blast Furnace control block, placed in the middle of a side
 * 1 Maintenance Hatch
 * 1 or more Input Buses
 * 1 or more Output Buses
 * 1 or more Energy Hatches
 * 0-4 Heat Proof Machine Casings, occupying the space not used by the other components

Cupronickel Coils have a Heating Capacity of 1800 Kelvin.

Kanthal Coils have a Heating Capacity of 2700 Kelvin.

Nichrome Coils have a Heating Capacity of 3600 Kelvin.

Do not mix different types of Heating Coils.

All Electric Blast Furnace recipes consume either 120EU/t or 500EU/t. However, the MV Energy Hatch requires Aluminium to craft, and Aluminium cannot be smelted outside an EBF. Therefore, the first time an EBF is constructed, in order to operate, its structure must contain 3 LV Energy Hatches. (Two would be enough ordinarily, but if any Maintenance problems are present, the EBF's energy consumption jumps from 120EU/t to 132EU/t, greater than the 128EU/t afforded by two LV Energy Hatches.)

As with all other GregTech multiblock machines:
 * Insufficient energy supply will destroy the currently processed material.
 * When the Output Bus is full, the Electric Blast Furnace will continue to work and will destroy all newly produced items.
 * Do NOT build a multiblock machine over chunk borders. Doing so can lead to unpredictable behavior. If you have NEI installed (which you should), chunk borders can be viewed by pressing F9 (by default).
 * Before using the Electric Blast Furnace for the first time, maintenance must be performed.
 * To activate or deactivate the Electric Blast Furnace, hit its control block with a Soft Hammer.
