The circulating fluidised bed boiler has a number of significant advantages in biomass applications, not least its high degree of fuel flexibility, ability to make use of locally sourced cheap but low quality fuels, and insensitivity to big variations in fuel properties.

When reduction in CO2 emissions, and emissions in general for that matter, is given priority, biomass fuel, co-fired with coal or used in a dedicated 100% biomass facility, can be an attractive option. However, the term “biomass” necessarily describes a broad range of organic materials. Biomass fuels may include clean wood chips from harvested trees, agricultural residue, salvaged wet forest residues, and manufacturing wood wastes that are very difficult to reliably burn, as well as mixtures of products. Also, the properties of the biomass vary substantially depending on seasonal mixtures, moisture content, and the region where harvested, as well as any fuel pre-processing necessary prior to firing. Biomass can have a wide range of chemical and physical properties and is a much more diverse fuel than coal.Read full article
