1. Fuel flexibility
-
Can burn a wide variety of solid fuels, from low-cost wastes to conventional fossil fuels.
-
Suitable fuels include coal (even poor grades), biomass, petroleum coke, anthracite mining waste (culm), oil shale, tar sands, coal slurries, and agricultural residues.
-
Can use various limestone sorbents to capture sulphur, making it adaptable to fuel market changes.
2. Lower installation cost
-
Modular design makes on-site installation faster and cheaper.
-
Easier to modify or scale without major redesign.
3. Low emissions
-
Very low NOₓ production due to lower combustion temperatures.
-
Can remove SO₂ during combustion by adding sorbents to the bed, reducing need for expensive post-combustion controls.
-
Achieves low particulate emissions.
4. High combustion efficiency
-
Stable and complete combustion even with varied fuel qualities.
5. High availability
-
Reliability often exceeds 95% when systems are properly sized and maintained.
6. High turndown ratio
-
Can efficiently operate under fluctuating load demands.
7. Combined cycle capability
-
Pressurized Fluidized Bed Combustion (PFBC) can integrate with gas turbines for highly efficient combined-cycle systems.
8. Compact plant layout
-
Requires smaller building volume compared to conventional boilers.
9. Advanced control systems
-
Better automation and process control improve efficiency and operational flexibility.
10. Ability to burn hazardous wastes
-
Safely disposes of certain industrial and municipal wastes while recovering energy.
11. Co-firing capability
-
Can co-fire refuse-derived fuel (RDF) with other fuels.
12. Low operating costs
-
Lower fuel costs due to fuel flexibility and lower costs for emission control.
13. Short construction time
-
Modular designs speed up project timelines.
14. Low cost of electricity
-
Overall lower fuel and operating costs contribute to cheaper power production.
15. Better ash quality
-
Produced ash is generally non-toxic, improving handling and potential reuse.
