The Large Turbine is a multiblock generator added by GregTech 5 Unofficial. It is capable of producing large amounts of Energy Units (EU). It comes in 4 variants: Steam, High Pressure, Gas, and Plasma. The amount of Steam/Gas/Plasma used depends on the Turbine built in. It slowly speeds up, so it should be used for constant Energy supply.

The main Turbine block changes the fluids the turbine can run with.

• A Large Steam Turbine runs on Steam and IndustrialCraft 2 Steam and will output Distilled Water in addition to the Energy Units.
• A Large High Pressure Turbine runs on Superheated Steam from IC2 (can also be produced with Large Heat Exchanger) and will output regular Steam in addition to the Energy Units.
• A Large Gas Turbine runs on Methane, Hydrogen and Biogas.
• A Large Plasma Generator runs on all types of plasma generated in the Fusion Reactor.

The Large Turbine requires a turbine rotor. Turbine rotors vary greatly in size and material and contribute efficiency, durability and optimal flow modifiers to the running of the turbine.

• Durability: About every 3000 ticks, the turbine takes 20% of the EU/t generated damage. In the Plasma Generator the damage is $\frac{EU}{t}^{0.7}$.
• Durability in latest GT5U: About every 1000 ticks, the turbine takes 20% or $\frac{EU}{t}^{0.6}$(whatever is smaller) of the EU/t generated damage.
• Efficiency: A percentage factored into the power output of the turbine.

• Optimal Flow: How much steam/gas/plasma/lava is required to attain ideal power production

Building the Multiblock

Build the edges of a 3x3x4 Block with Turbine Casings

The Main Turbine Block comes in the front Center, the surrounding blocks become a turbine texture

The Large Turbine is assembled as a 3x3x4 (long) multiblock structure. The entire frame must be made from Turbine Casings.

The Front-Center of the multiblock must be a Main Turbine Block. The Back-Center must be a Dynamo Hatch.

The sides (including top and bottom) must include:

• 1 or more Input Hatches
• 1 Output Hatch (required for Steam and High Pressure turbines)
• 1 Maintenance Hatch
• 1 Muffler Hatch (required for Gas Turbine)

The remaining sides are Turbine Casings. The two center blocks remain air blocks. The 9 Blocks in front of the Turbine also must be air blocks.

After that, a Turbine must be placed in the top-right slot in the turbine gui. After fixing the maintenance issues in the maintenance hatch, the turbine can be started with a hit from a soft hammer.

Once the turbine has been started, it will continue in "On" mode until it is deactivated (intentionally or otherwise). It will not deactivate by running out of steam.

Rotors

This table lists the attributes of all available turbine materials. The "Flow" attribute given is the optimal L/sec for Steam Turbines. To find the optimal EU/t for Plasma Turbines, multiply the "Flow" attribute by 2. To find the optimal EU/t for Gas Turbines, divide the "Flow" attribute by 20.

Optimal Flow and Nominal Output

Optimal Flow is the flow rate required to achieve optimal output for the turbine. Each turbine rotor has a specific optimal flow rate, which is further defined by the type of turbine it is installed in (Steam vs HP Steam vs Gas vs Plasma). It is important to understand that the "Optimal Steam Flow" displayed on the tooltip for a Turbine Rotor is specific to the Large Steam Turbine. Optimal Flow for all Large Turbine types (including Steam) is calculated as:

$\text{Optimal Flow} = \frac{\text{Nominal Output}}{\text{Fuel Value}}$

Nominal Output

To determine nominal flow rate, the actual nominal output must first be determined. Each Large Turbine type has a multiplier to the stated (tooltip) Optimal Steam Flow which is used in the calculation.

Turbine Type	Nominal Output
Steam	Optimal Steam Flow / 2
HP Steam	Optimal Steam Flow
Gas	Optimal Steam Flow
Plasma	Optimal Steam Flow * 40

Nominal Output Examples

• A Large Steam Turbine using a "10000 L/sec" turbine item has a nominal output of (10000/20) / 2 = 250 EU/t.
• A Large Gas Turbine using a "10000 L/sec" turbine item has a nominal output of (10000/20) = 500 EU/t.
• A Large Plasma Turbine using a "10000 L/sec" turbine item has a nominal output of (10000/20) * 40 = 20000 EU/t.
• A Large Plasma Turbine using a "40000 L/sec" turbine item has a nominal output of (40000/20) * 40 = 80000 EU/t.

(Flow is divided by 20 to get the rate in volume per tick instead of volume per second)

Fuel Values (not all listed)

Fuel Type	Value
Steam	0.5 EU/L
HP Steam	1 EU/L
Biogas	32 EU/L
Helium Plasma	4096 EU/L

Calculation

Using $\text{Optimal Flow} = \frac{\text{Nominal Output}}{\text{Fuel Value}}$

Steam: $\frac{10000 L/s}{2} \div / (0.5) = 10,000 L/s\ or 500 L/t$

Biogas: $\frac{10000 L/s}{32} = ~312 L/s\ or ~16 L/t$

Helium Plasma: $\frac{10000 L/s \times 40}{4096} = ~98 L/s\ or ~5 L/t$

Efficiency

A turbine's actual output is $\frac{\text{Nominal Output} \times \text{Efficiency} }{100}$. $\text{Efficiency}$ is expressed as a percentage. A turbine can work with up to 150% of its optimal flow, but no power will be generated from the surplus. If supplied with less, the turbine will still run, but an additional efficiency modifier will be applied to the output as $\text{Flow Efficiency} = \frac{\text{ActualFlow}}{\text{Optimal Flow}}$. Therefore A Large Gas Turbine using a "10000 L/sec 110% Efficiency" turbine rotor has a actual output of $(10000 EU/t \div 20) \times 1.10 = 550 EU/t$.

Spin Up / Spin Down

Large Turbines have a spin up time of 50 seconds and slow down over a period of 10 seconds, at which point they are not operating at full efficiency.
