Biomass Power Steam Turbines
Dongfang’s GSS, GTS and XTS steam turbine families for biomass power generation. Compare the named series separately, preserving each arrangement’s power, pressure and speed notation from the manufacturer’s catalogue.
- Named families
- GSS / GTS / XTS-I / XTS-II / XTS-III
- Pressure notation
- MPa.a — absolute pressure
- XTS-II arrangement
- Dual cylinder / dual speed
PRODUCT OVERVIEW
Biomass Power.
The biomass section identifies duties associated with crop straw, wood, energy crops and production wastes. Its five named turbine families have separate parameter entries.
Compare GSS, GTS and the XTS arrangements using the steam supply and electrical duty of your project. CHENDA coordinates the required information and manufacturer clarification.
CATALOGUE REFERENCE
Series parameters.
Compare each row as a separate catalogue reference. Final selection depends on the complete operating duty.

| Series / arrangement | PowerMW | Inlet / reheat notation | Exhaust pressure / mode | Speedrpm | SourcePDF page | Enquiry |
|---|---|---|---|---|---|---|
| GSS — whole-unit shipment | 10–50 | 8–14 MPa.a; temperature: Not stated | Not stated | ≤8000 | p. 21 ↗ | |
| GTS | 30–100 | 8–14 MPa.a; temperature: Not stated | Not stated | 3000 | p. 21 ↗ | |
| XTS-I — dual cylinder / high speed | 20–80 | 8–14 MPa.a; temperature: Not stated | Not stated | Not stated | p. 21 ↗ | |
| XTS-II — dual cylinder / dual speed | 20–60 | 8–14 MPa.a; temperature: Not stated | Not stated | 5025 / 3000 | p. 21 ↗ | |
| XTS-III | 45–100 | 8–14 MPa.a; temperature: Not stated | Not stated | 3000 | p. 21 ↗ |
The five families do not form one universally interchangeable operating range.
The family parameter blocks do not state exhaust pressures or full inlet and exhaust flow schedules.
Whole-unit shipment is a catalogue arrangement description, not a stock, delivery-time or logistics commitment.
Full source reading notes
Source: S01, PDF physical pages 10–23. Parameter rows are on pp.10, 11, 13, 15, 18, 19, 21 and 22–23; each row retains its own source page. The general source link opens the first relevant page, p.10.
Each row is a separate catalogue series, arrangement or explicitly labelled section overview. Descriptive arrangement names are not invented model numbers. Values from different rows must not be combined into one operating duty.
An upper limit such as ≤100 MW does not state a minimum power. Temperatures are reproduced without adding an independent ≤ symbol where the source does not show one. The 24.2 MPa value for the 80–200 MW residual-heat row is reproduced without adding ≤.
Biomass inlet pressure is explicitly 8–14 MPa.a (absolute). Other pressure entries retain MPa because the catalogue does not identify absolute or gauge pressure for those rows.
The catalogue cover describes 100 kW–200 MW, while the solar-thermal DCSP-3 row on p.15 explicitly states 350–660 MW. Keep both source scopes distinct: 200 MW is not a universal limit for every product, and DCSP-3 does not extend the combined-cycle or mechanical-drive families to 660 MW.
For cogeneration on p.13, "suction" is retained from "Back pressure (suction) units"; it is not silently reinterpreted as an extraction guarantee. The exhaust statement "as low as 0.1 MPa" and the extraction-condensation-back-pressure mode are retained separately.
For the dual-speed waste-to-energy row on p.19, ~13 MPa is an approximate inlet value, not 6–13 MPa or ≤13 MPa. The speed notation 5000 / 3000 rpm is not a continuous speed range.
For biomass XTS-I on p.21, high-speed operation is described but no numerical speed is stated. XTS-II explicitly lists 5025 / 3000 r/min, reproduced here under the rpm column. Do not borrow numerical values from adjacent series.
The combined-cycle overview combines page-specific references, not an equipment selection matrix: p.22 states power ≤200 MW and speed ≤13000 rpm; p.23 states high-parameter design up to 16 MPa / 600℃. The brochure does not establish that all these limits occur together in one model.
Not stated means that the relevant series parameter block gives no value. Development timelines and project examples are not additional product-series ranges. ORC and natural-gas differential-pressure products use different working fluids and are not merged into this steam-turbine table.
Series scope.
- The GSS entry identifies whole-unit shipment as an arrangement characteristic.
- XTS-I is described as dual-cylinder and high-speed; its parameter block does not state a numerical speed.
- XTS-II has a distinct dual-speed notation; it is not combined with the single-speed values of other families.

Questions about this series.
What does MPa.a mean in these rows?
The biomass parameter blocks explicitly use absolute pressure. State the pressure reference in your enquiry so that the available steam conditions can be compared consistently.
Are inlet temperature and numerical speed stated for every series?
The cited family blocks do not independently list inlet temperatures, and XTS-I gives no numerical speed. Retain those omissions rather than copying values from adjacent families.
