Techno-economic analysis of PC versus CFB combustion ...

2019-12-11 · For example, if the price of higher quality imported coal becomes too great, a switch to lower grade locally-sourced coal can be made without significantly impinging on the performance of a CFB boiler. In this way, the flexibility of CFBC can act as a contingency against variation in fuel supply and potentially offers an economic edge over PCC.
