Integrated coal gasification combined cycle (IGCC) has the advantage of high coal type compatibility compared to conventional pulverized coal-fired power generation, and high-power generation efficiency can be obtained even when low-grade coal is used. However, the use of a wide variety of coals generates slag with different melting points (RFT), which may cause pipe blockage. To prevent this problem, we attempted to predict the RFT in advance using machine learning. As a result of predicting the RFT from the coal property values, we obtained the result that the prediction was possible with an RMSE of 26.74°C (prediction error of 2.1%).
