Model D400 and D600 - High-Efficiency Steam Turbines
From Steam Turbines
Our D400 and D600 type steam turbines primarily support F-class and H-class gas turbine plants. They were developed for high-efficiency power generation at larger single-shaft or multi-shaft plants and for sites with low to very-low exhaust pressure. The D type steam turbines feature a combined high pressure (HP)/intermediate pressure (IP) section and either one or two double-flow low pressure (LP) sections.
Engineered to Meet Your Needs
Engineered to Meet Your Needs
- Main steam inlet pressure up to 2400 psi accommodates the highest available heat recovery steam generator steam pressures to enable high efficiency
- HP or IP temperatures up to 1112°F, enables highest steam turbine efficiencies
- High-efficiency last-stage blades selected to accommodate site-specific backpressure conditions
Architecture for Performance
- Combined high pressure/intermediate pressure section for compact footprint and high power density
- One or two low pressure, double-flow modules for sites with low/very-low exhaust pressure allows the steam turbine to be engineered to meet site specific conditions for optimal performance
- Low pressure configurations for side-flow or down-flow exhaust provide plant layout flexibility
- Compact and cost-effective configurations in both multi-shaft and single shaft. Single shaft configuration incorporates a clutch that enables high plant operational flexibility and maintainability
- Wide range of last-stage bucket sizes, up to 45-inch 60 Hz and 55-inch 50 Hz, that enable application of D400 and D600 turbines over a large spectrum of exhaust pressures
Experience You Can Rely On
- 230 units in the field, since 1969
- Experienced in 50 Hz and 60 Hz environments
