Q. With reference to the Biomass Co-firing, consider the following statements;
1.In this Coal and biomass are combusted together in boilers that have been designed to burn coal without any retrofitting.
2.It is a cost-effective method for decarbonising a coal fleet.
3.Biomass pellets can be stored for long durations at the plant.
Which of the statements given above is/are correct?
Answer: C
Notes:
Statement 1 is incorrect: Coal and biomass are combusted together in boilers that have been designed to burn coal. For this purpose, the existing coal power plant has to be partly reconstructed and retrofitted.
Statement 2 is correct: Biomass co-firing is a globally accepted cost-effective method for decarbonising a coal fleet.
Statement 3 is incorrect: It is challenging to store biomass pellets for long durations at the plant sites since they absorb moisture from air quickly, rendering them useless for co-firing. Only pellets with up to 14% of moisture can be used for combustion along with coal.
