Large Turbine/zh-cn

大型涡轮是所追加的多方块发电设备，可产生大量EU电力. 有四种类型，分别是：蒸汽、高压、燃气和等离子. 涡轮机的蒸汽/燃气/等离子消耗量取决于涡轮机本身：涡轮机工作速度本身会慢慢提升，所以其消耗也是固定的.

The main Turbine block changes the fluids the turbine can run with.
 * A Large Steam Turbine runs with Steam and (IC2).
 * A Large High Pressure Turbine runs with Superheated Steam from IC2 (can also be produced with ).
 * A Large Gas Turbine runs with Methane, Hydrogen and Biogas.
 * A Large Plasma Generator runs with all types of plasmas generated in the.

The Large Turbine also 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 EU/t^0.7.

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


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.

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:

Optimal Flow = Nominal Output / 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.

Nominal Output Examples
(Flow is divided by 20 to get the rate in volume per tick instead of volume per second)
 * A Large Steam Turbine using a "10000L/sec" turbine item has a nominal output of (10000/20) / 2 = 250 EU/t.
 * A Large Gas Turbine using a "10000L/sec" turbine item has a nominal output of (10000/20) = 500 EU/t.
 * A Large Plasma Turbine using a "10000L/sec" turbine item has a nominal output of (10000/20) * 40 = 20000 EU/t.
 * A Large Plasma Turbine using a "40000L/sec" turbine item has a nominal output of (40000/20) * 40 = 80000 EU/t.

Fuel Values (not all listed)

Calculation
Using Optimal Flow = Nominal Output / Fuel Value

Steam: (10000 / 2) / (0.5) = 10,000 L/s or 500 L/t

Biogas: (10000) / (32) = ~312 L/s or ~16 L/t

Helium Plasma: (10000 * 40) / (4096) = ~98 L/s or ~5 L/t

Efficiency
A turbine's actual output is Nominal Output * Efficiency% / 100. 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 FlowEfficiency = ActualFlow / OptimalFlow.

Therefore A Large Gas Turbine using a "10000L/sec 110% Efficiency" turbine rotor has a actual output of (10000/20) * 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.
