Combined-Cycle Steam Turbines
Dongfang steam turbines for gas-steam combined-cycle projects, using steam generated from gas-turbine exhaust heat. The catalogue provides a section-level capability overview; final equipment selection requires the actual steam cycle and interfaces.

PRODUCT OVERVIEW
Combined Cycle.
Gas-turbine exhaust heat is used to generate steam in a heat-recovery boiler, and that steam drives the steam turbine. The catalogue places this application within distributed-energy projects.
The available parameter entry is a section overview rather than an individual model schedule. CHENDA coordinates the steam-cycle duty and supply-interface questions with the manufacturer.
CATALOGUE REFERENCE
Series parameters.
Compare each row as a separate catalogue reference. Final selection depends on the complete operating duty.
Scroll the table horizontally to see every parameter, source and enquiry link.
| Series / arrangement | PowerMW | Inlet / reheat notation | Exhaust pressure / mode | Speedrpm | SourcePDF page | Enquiry |
|---|---|---|---|---|---|---|
| Gas-steam combined cycle — section overview | ≤200 | Up to 16 MPa / 600℃ (section overview, p.23) | Not stated | ≤13000 | p. 22, 23 ↗ |
The source pages provide an overview, not a named-model table or a guarantee that every stated limit can be reached simultaneously.
The project examples contain slash-separated parameter strings without a complete unit key; those strings are not silently relabelled as inlet, reheat or flow values.
Other equipment manufacturers shown in the catalogue are not represented as CHENDA agencies or supply authorizations.
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 overview gives power and speed references separately from the high-parameter design statement.
- The associated project examples describe individual installations; their values do not create a continuous series range.
- The gas turbine, heat-recovery boiler and steam turbine have distinct equipment interfaces and supply boundaries.

Questions about this series.
Do all of the overview limits apply together to one machine?
The brochure does not provide that selection matrix. Power and speed appear on one page, while the high-parameter design statement appears on the next; the actual duty requires manufacturer assessment.
Does this page include a gas turbine and a heat-recovery boiler?
This page describes the steam-turbine side. State which packages and interfaces your enquiry includes so that the equipment and contracting scope can be defined.
