  1. The Babcock & Wilcox CompanyFastCirc™ HRSG • June 12, 2014

  2. HRSG Side Viewwith FastCirc™ Vertical Separator FastCirc™ Vertical Separator Single row harps Optimized SH and RH drains

  3. FastCirc HRSG Arrangement • Reduced crane requirements during construction • Increased personnel safety in operation • Performs the same function of an HP Steam Drum • Reduces shell and connection stresses during fast start and rapid load changes

  4. Drawbacks of Conventional HP Drum • Thick Walls (~6”-7” for a 2400 PSI Unit) – Limits startup time / HP drum life • Drum hump during startup and transients

  5. Patented FastCirc™ Vertical Separator • Vertical Separator Benefits: • Performs the same function as an HP steam drum • Thin Walls • Increased Response to Load Changes • Eliminates Drum Hump Problems • Expands in the vertical direction (same as tube bundles)

  6. Patented FastCirc™ Vertical Separator • Vertical Separator Benefits: • Thin walls (~3” for 2400 PSI Units) • Expands in the vertical direction (same as tube bundles) • Integral internals • Same steam purity and holding capacity as conventional drum

  7. Fatigue Life UsageFastCirc Vertical Separator vs. HP Steam Drum • Hot start ≤ 8 hours • Warm start > 8 hours and ≤ 72 hours • Cold start > 72 hours Typical Gas Turbine Ramp Rate for Hot Startup Press. Psig, Temp °F Flow % Time (minutes)
