IGCC For Brown Coals with Supercritical Steam Turbine
Original language description
The paper deals with the IGCC for brown coal (BC) with simultaneous improvement of the steam cycle by the usage of supercritical steam parameters. Two gasifiers with a fluidized bed are used with outlet syngas temperature about 900 °C. Main part of the paper is focused on the arrangement and optimization of the IGCC with net total electrical output 454.7 MW and with supercritical inlet parameters 260 bar, 580°C/600°C of steam turbine. The energy sources for the steam part of the cycle are HRSGs downstream of two gas turbines at 122.6 MW each and two raw gas coolers downstream of two gasifiers. The thermal efficiency of this IGCC is on LHV basis about 49.0%. Utilization of brown coal (BC) energy m described IGCC is by 4.7% higher than m steam power station with the same parameters. This IGCC enables reduction of CO2 emission by around 44% compared with existing power stations with thermal efficiency 34%.
