# Gas-turbine-driven compressor train

Mechanical-drive train: a two-shaft gas turbine in an acoustic enclosure (filter house with weather hoods and filter stages, exhaust silencer and stack, fuel gas skid, lube console with fin-fan cooler, internal monorail) driving an API 617 barrel or horizontally split centrifugal compressor through a guarded coupling, with anti-surge valve, suction strainer and dry gas seal panel. A preset of `centrifugal-compressor` with the gas-turbine driver.

**Standards:** API 616, API 617, API 614, API 692, API 671, ASME B16.5

## Installation

```bash
npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz add gas-turbine-compressor
```

Copies `rotating/gas-turbine-compressor.tsx`, any helper files it imports and the shared `lib/` into `src/components/deck-twin/`. Needs `three`, `@react-three/fiber` and `@react-three/drei`.

## Usage

```tsx
import { Canvas } from '@react-three/fiber'
import { OrbitControls } from '@react-three/drei'
import { Stage } from './components/deck-twin/lib/stage'
import { GasTurbineCompressor } from './components/deck-twin/rotating/gas-turbine-compressor'

export default function Scene() {
  return (
    <Canvas shadows camera={{ position: [8, 5, 9], fov: 35 }}>
      <Stage>
        <GasTurbineCompressor doorsOpen={true} />
      </Stage>
      <OrbitControls makeDefault />
    </Canvas>
  )
}
```

## P&ID

A gas turbine (narrowing trapezoid, combustor box with the fuel line, widening trapezoid) coupled by its shaft to a compressor trapezoid, wide end at suction; anti-surge recycle and blowdown lines around the compressor.

A compressor coupled to a motor circle with M is the motor-driven version (centrifugal-compressor). A turbine coupled to a G circle is a gas-turbine-generator.

API 616 gas turbine + API 617 compressor datasheets fields and the props they set:

| Field | Prop |
| --- | --- |
| Suction nozzle size | `suctionNps` |
| Discharge nozzle size | `dischargeNps` |
| Flange rating | `rating` |
| Turbine rated power | `mw` |

| Nozzle orientation | `nozzles` |
| Tag number | `tag` |
