Turbines
Gas turbines, from grid to site.
Gas turbines power baseload plants for national grids and run on skids at data centres, oil fields and industrial sites. Here is how a plant works, and how our turbine programme fits in.
How it works
Inside a combined-cycle plant.
A gas turbine makes power directly. In combined cycle, its hot exhaust raises steam to drive a second turbine. Switch modes and select a stage to follow the energy through the plant.
Air inlet
Air is filtered and conditioned before it enters the turbine. Clean air protects the compressor and keeps output steady at hot, dusty or coastal sites.
Compressor
A multi-stage axial compressor raises the pressure of the air many times over. It takes roughly half of the turbine's own work to drive it.
Combustor
Fuel is injected and burned with the compressed air. Modern combustors run on natural gas or dual fuel and are designed for low emissions.
Gas turbine
Hot gas expands through the turbine, turning the shaft that drives both the compressor and the generator. The exhaust still leaves at around 500 to 600 °C.
Generator
The shaft drives an electrical generator. In simple cycle this is the plant's only output. In combined cycle it supplies about two thirds of it.
Heat recovery steam generator
Instead of venting hot exhaust, the plant passes it over banks of water-filled tubes to raise high-pressure steam.
Steam turbine
Steam drives a second turbine and generator, adding about half as much again to the plant's output with no extra fuel.
Condenser and feedwater
Spent steam is cooled back to water, by air or by sea or river water, and pumped back to the heat recovery steam generator to repeat the cycle.
Typical values for modern plant. Actual figures depend on equipment, site and climate.
Aeroderivative programme
Aviation engineering, put to work on the ground.
Aeroderivative gas turbines share their core with jet engines. They are compact, start in minutes and follow load closely. Our programme draws on the DTX group's aviation engineering experience to supply them where they are needed. Select an application.
Peaking and grid support.
Units in a utility plant cover the evening peak, back up larger plant and steady grids with a growing share of solar and wind. Several can be combined with heat recovery for combined-cycle output.
- Starts in minutes
- Efficient at part load
- Phased additions as demand grows
Power before the grid arrives.
New data centres often wait years for a grid connection. On-site turbines on skids provide prime or backup power from day one, and can stay as resilience once the grid connects.
- Prime or bridging power
- High availability with multiple units
- Small footprint per megawatt
Turning field gas into power.
On oil and gas fields, turbines run on gas produced on site to power pumps, compression and processing, reducing flaring and diesel use.
- Runs on field or pipeline gas
- Mechanical drive or power generation
- Rugged skid packages for remote sites
Reliable power for heavy loads.
Mines, smelters and process plants need large, steady loads that weak grids cannot always supply. On-site generation removes that constraint.
- Off-grid or grid-parallel operation
- Heat recovery for process steam
- Long-term power supply contracts
Capacity in months, not years.
When a grid faces a shortfall, trailer- or skid-mounted units can be shipped and connected quickly, then moved or kept as permanent capacity.
- Ships by road or sea
- Minimal site works
- Redeployable as needs change
Why now
Gas turbines are in short supply, and lead times for new units are years long.
Demand for gas-fired generation is rising worldwide, driven by data centres, industrial growth and the retirement of coal plants. Manufacturers' order books are full, and many projects cannot wait for new units.
Our programme draws on the DTX group's aviation engineering experience to offer a faster route to proven turbine capacity, for DTX Power projects and for utilities, developers and industrial users.
In development. We welcome early conversations with prospective users and partners.
