5. Biomass Conversion Technologies

substituting biomass for a portion of the coal in an existing power plant boiler. It is the most economic near-term option for introducing new biomass power generation. Because much of the existing power plant equipment can be used without major modifications, cofiring is far less expensive than building a . new biomass power plant.

Economic and Environmental Impact of Biomass Types for

lower content in biomass than in coal. The high volatile and low fixed carbon content makes biomass a highly reactive fuel which makes biomass burnout faster than coal. Boiler design should ensure that the volatile content undergoes complete combustion to improve efficiency and reduce incomplete combustion related emissions.

A strategy for converting coal fueled power plants to

Conversions of coal plants to use biomass have typically been in stoker / fluid bed plants because the biomass fuel is wood chips. Wood chips are less expensive than wood pellets. But wood chips cannot easily be used as fuel in a pulverized coal plant. Wood pellets can easily be milled to the same powder consistency as pulverized coal.

Biomass and the environment U.S. Energy Information

Using biomass for energy has positive and negative effects. Biomass and biofuels made from biomass are alternative energy sources to fossil fuels—coal, petroleum, and natural gas. Burning either fossil fuels or biomass releases carbon dioxide (CO2), a greenhouse gas.However, the plants that are the source of biomass for energy capture almost the same amount of CO2 through photosynthesis
