An ultrasupercritical coalfired power plant (USC) is the host unit for the CCS to enhance the efficiency of coalfired power plants integrated with the carbon capture system. The live steam temperature is 650 °C. The schematic with/without CCS is shown in Fig. 3 and the main operating parameters are listed in Table 2.
On average, it is between 40% and 44% for coal plants, 20% to 25% for biofuel/gas plants, 35% to 40% for single gas turbines (oil or gasfired), and from 55% up to even 63% for combined cycles which are the most efficient thermal power plants. (IEA 2018). 2.
The dimensions and operating conditions used for this simulation do not represent any specific coalfired power plant. This model is for demonstration and tutorial purposes only. Before looking at the model, it may be useful to look at the process flow diagram (PFD). SCPC Power Plant (simplified description) Inputs: Throttle valve opening,
