Hot-gas cleanup for coal-based gas turbines

This article describes a gas turbine combined-cycle system, linked by a hot-gas cleanup process to an advanced coal-conversion system. Integrated gasification combined-cycle (IGCC) and pressurized fluidized-bed combustion (PFBC) are two examples of types of new-generation advanced coal-fired power plants. In these plants, coal-derived gases are cleaned prior to or during combustion at elevated pressures and temperatures, which makes them compatible with gas turbine power generation systems. Such gas turbine systems will achieve exceptional efficiencies by the end of the decade, assisted by a government-sponsored advanced turbine system (ATS) initiative. In commercially available IGCC systems, superior environmental performance has already been achieved. With the adaptation of hot-gas cleanup, large-scale demonstration plants will achieve 45 percent efficiency by the turn of the century. IGCC plant efficiencies will climb to 52 percent and greater as advanced turbine systems are incorporated.
