Integrated Gasification Combined Cycle (IGCC) Dynamic Simulator
The AVESTAR® center offers courses using the Integrated Gasification Combined Cycle (IGCC) Dynamic Simulator. The IGCC simulator builds on and reaches beyond existing combined-cycle and conventional-coal power plant simulators to combine--for the first time--a Gasification with CO2 Capture process simulator with a Combined-Cycle power simulator together in a single dynamic simulation framework. The AVESTAR® center IGCC courses provide unique, comprehensive training on all aspects of an IGCC plant, illustrating the high-efficiency aspects of the gasifier, gas turbine, and steam turbine integration.

Provost, "AVESTAR Center: Dynamic Simulation-based Collaboration Toward Achieving Operational Excellence for IGCC Plants with Carbon Capture,” Proc. of the 29th Annual International Pittsburgh Coal Conference, Pittsburgh, PA, October 15-18 (2012).
The dynamic simulator is based on the reference plant design designated as IGCC Case 2 in the DOE/NETL report “Cost and Performance Comparison of Fossil Energy Power Plants Volume 1, Bituminous Coal and Natural Gas to Electricity Final Report (DOE/NETL-2010/1397), Rev. 2, November 2010.” More detailed process descriptions for all major plant areas are available in “DOE/NETL IGCC Dynamic Simulator Research and Training Center, Volume 2: IGCC Process Descriptions, June 30, 2008 (DOE/NETL-2008/1324).”
The IGCC plant design is based on slurry-fed, entrained-flow gasification technology with 90% pre-combustion CO2 capture. Each of the two gasification trains consists of a cryogenic distillation-based air separation unit (ASU), entrained-flow gasifier with radiant syngas cooler (RSC), syngas cleanup for particulates and mercury removal, water gas shift reactors, dual-stage physical solvent-based acid gas removal (AGR) process for H2S and CO2 capture, Claus plant for sulfur recovery; and CO2 conditioning and compression. The simulator allows for coal, petroleum coke, and biomass feedstocks, with the capability to add more feedstocks upon request. The combined cycle uses advanced F-class gas turbines and a triple pressure-level heat recovery steam generator (HRSG)/steam cycle. The simulator also includes condensate, feed water, and circulating water systems.
The IGCC Dynamic Simulator handles normal base load operation, complete cold, warm, and hot startups, normal shutdown, load shedding and following, and fuel switching. The dynamic simulator also handles emergency shutdowns and other abnormal situations in real-time, including equipment malfunctions and failures, together with changes initiated through actions from the instructor station or from field operators.
Key operational capabilities of the IGCC Simulator include:
- Normal base load operation
- Complete cold, warm, and hot startup
- Normal shutdown
- Fuel switching
- Emergency shutdowns
- Load shedding and following
- Equipment malfunctions and failures
- Variety of abnormal situations in real-time
