Co-firing should not be confused with the use of multiple fuels in boilers designed to burn multiple fuels. Multiple fuel boilers, such as those commonly installed and used as “power boilers” at pulp mills, are designed to burn a wide range of fuels such as coal, fuel oil, natural gas, whole tree chips, mill residues, Continue Reading

The term “biomass” refers to materials derived from plant matter such as trees, grasses, and agricultural crops. These materials, grown using energy from sunlight, can be renewable energy sources for fuelling many of today’s energy needs. One of the most attractive and easily implemented biomass energy technologies is co-firing with coal in existing coal-fired boilers. Continue Reading
