- •
Heat integration between the water gas shift unit and the gasification unit is put forward.
- •
The specific coal consumption and the specific oxygen consumption decrease by 2.7% and 6.5%.
- •
The energy conversion efficiency of HIS and NHIS are nearly the same.
- •
The exergy efficiency of HIS (62.66%) is better than that of NHIS (62.02%).
