The supercritical 600MW steam turbine mainly has four series, including three-cylinder four-exhaust with combined HIP module, two-cylinder two-exhaust with combined HIP module, three-cylinder two-exhaust with split HP&IP module and four-cylinder four-exhaust with split HP&IP module. It can adapt to water cooling or air cooling, and can provide appropriate amount of industrial extraction and heating extraction.
Typical steam inlet parameters 24.2MPa/566°C/566°C, and the rated back pressure ranges from 3.4kPa to 30kPa;
The orders and Commercial operation performance both exceeded 100 units, of which more than 20 are overseas. Typical projects include Huaneng Weijiamao project, Pakistan Sahiwal project etc.
