A review of biomass co-firing in North America
The net electric efficiency of a typical biomass co-firing plant usually ranges from 35–44%. Evidence shows that direct co-firing is usually slightly more efficient (roughly 2% more) than the other co-firing technologies due to the conversion losses that occur in the biomass gasifiers and boilers [10].

Biomass Co-firing in Coal Power Plants
Biomass co-firing consists of combusting biomass and fossil fuels, mostly coal but also natural gas, in the same power plant. In most cases, biomass co-firing in coal power plants takes place by mixing biomass with coal before the burners, but biomass can also be gasified and burned in separate burners, after which the gaseous fuel or steam is ...

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.
