| Popis: | Integration of coal-fired power plants with NH3-based CO2 capture is a promising technology for CO2 capture. However, the output and efficiency of the original coal-fired power plant are reduced because the integration requires energy. This work studied three typical coal-fired power plants with the capacities of 330, 660, and 1000 MW and turbine levels of N330-16.67/538/538, N660-24.2/566/566, and N1000-25/600/600, respectively. The integration of these coal-fired power plants with the same NH3-based postcombustion CO2 capture system was established. Heat consumption, energy penalty, and other evaluation indicators were obtained through an Ebsilon simulation. Among the three coal-fired power plants, the thermal efficiency of 1000 MW is the highest, whereas that of 330 MW is the lowest. The energy penalty of the 660 MW coal-fired power plant is the highest, whereas that of 330 MW is the lowest. To fully analyze the integration performance of power plants with different capacities, comprehensive evaluation... |
