Model D400 and D600 -High-Efficiency Steam Turbines

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
