Solar Thermal Steam Turbines
Dongfang’s DCSP steam turbine families for solar thermal generation. Review the distinct DCSP-1, DCSP-2 and DCSP-3 arrangements using their own catalogue ranges, rather than treating them as one capacity band.

PRODUCT OVERVIEW
Solar Thermal.
The solar-thermal section identifies three DCSP families. DCSP-1 is described as dual-speed reheating, while DCSP-2 and DCSP-3 are described as double-cylinder reheating arrangements.
Each family follows its own power band. Define the steam-cycle and operating requirements first; CHENDA coordinates the relevant technical questions and manufacturer response.
CATALOGUE REFERENCE
Series parameters.
Compare each row as a separate catalogue reference. Final selection depends on the complete operating duty.

|---|---|---|---|---|---|---|
| DCSP-1 — dual-speed reheating | 25–80 | Not stated | Not stated | Not stated | p. 15 ↗ | |
| DCSP-2 — double-cylinder reheating | 100–200 | Not stated | Not stated | Not stated | p. 15 ↗ | |

DCSP-3 is a distinct solar-thermal family; its range does not extend the combined-cycle or mechanical-drive series.
The cited family rows do not give numerical shaft speeds or exhaust pressures. “Not stated” remains a genuine source limitation.
Operating flexibility descriptions are catalogue statements, not an agreed project performance guarantee.
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 catalogue assigns a separate power band to each DCSP family.
- DCSP-3 has its own inlet and reheating notation; that notation is not copied into the other two families.
- The section also discusses flexible operation, but those statements do not replace a project-specific operating schedule.

Questions about this series.
Does the brochure-cover power overview cap DCSP-3?
DCSP-3 has a separate, explicitly stated power band in the solar-thermal section. Use that family’s row rather than applying the cover overview to every product.
Can DCSP-3 inlet conditions be used for DCSP-1 or DCSP-2?
Those families do not have independently stated inlet conditions in the cited parameter block. Their project duty requires assessment without borrowing the neighbouring family’s values.
