Circulating Fluidized Bed Boilers (CFB)

A wide range of fuels can be burned efficiently, including low-grade and difficult-to-burn fuels such as anthracite, lignite, petroleum coke, oil shale, discarded coal, and biomass within a wide range of mixing rates

Relatively low and uniform furnace temperatures of approximately 850°C to 900°C.

Selective non-catalytic reduction (SNCR) systems can be added, leading to even lower NOx emissions.

Injection of prepared and dried limestone in the furnace.

Dry scrubber NID* achieving 98% sulfur removal while reducing limestone consumption.

Just-In-Time (JIT*) system for limestone drying and crushing available for direct limestone feeding.

Ultra-supercritical CFB

660 MWe for lignite B, higher for hard coal

• Ultra-supercritical 285 bar, 605°C/623°C (MS/RH)
• More than three points increased net plant 
• efficiency relative to subcritical
• 6% reduction of CO2 footprint 
• Inherent low NOx emission with our air staging 
• Low SO2 emission without backend treatment
• Designed for reliability:
  • Well-tested material for pressure parts with many years of onsite experience
  • Multiple fuel feeders and ash extraction ports
  • Standardized modules that allow changing outputs, fuels, and steam temperatures
