Biomass Co-firing
Biomass co-firing stands for adding biomass as a partial substitute fuel in high-efficiency coal boilers. Coal and biomass are co-combusted in boilers that have been designed to burn coal. For this purpose, the existing coal power plant has to be partly reconstructed and retrofitted. Co-firing is an option to convert biomass to electricity ...

Biomass Energy
Biomass can also be co-fired, or burned with a fossil fuel. Biomass is most often co-fired in coal plants. Co-firing eliminates the need for new factories for processing biomass. Co-firing also eases the demand for coal. This reduces the amount of carbon dioxide and other greenhouse gases released by burning fossil fuels.
