Volume 2 The generic IGCC power plant produces 746 MW gross (556-megawatt net) electric power and consists of dual-train gasifiers producing clean singes for combustion in two (2) F-class advanced combustion turbines with a combined net output of 464 MW. The exhaust of each combustion turbine (CT) is sent through a heat recovery steam generator (HRSG) and produces steam that is supplied to a steam turbine (ST) having a net output of 275 MW. A syngas expander supplies an additional 6.3 MW of net output. This document provides a conceptual design of the DOE/NETL IGCC Dynamic Simulator reference plant. In this context, conceptual design means that all of the major components and systems and the relevant control loops have been defined. The basis of the simulator conceptual design is the engineering model of the IGCC Power Plant included as Case 2 in the DOE / NETL?s report ?Cost and Performance Comparison of Fossil Energy Power Plants Volume 1, Bituminous Coal and Natural Gas to Electricity Final Report (DOE/NETL-2007/1281), Rev. 1 August 2007.? A Process Flow Diagram of Case 2 is presented below in Figure 1.
