  • Particulate waste wood fuel, method for making particulate waste wood fuel, and a method for producing energy with particulate waste wood fuel
    Patent number: 6193768
    Abstract: A particulate waste wood fuel comprising wood particles comprising less than 20% water by weight and having a particle size distribution suitable for combustion of the particulate wood fuel in a particulate fossil fuel suspension furnace. A method for making the particulate wood fuel includes shredding of waste wood and drying the shredded waste wood to obtain the desired particle size distribution and water content. A method for producing energy comprises injecting the particulate wood fuel into the combustion chamber of a particulate fuel suspension furnace separately from a particulate fossil fuel which is also injected into the combustion chamber. The particulate fossil fuel and particulate wood fuel are combusted in the combustion chamber in a gas flow through the combustion chamber to form a flame in the gas flow. The wood particles are substantially completely combusted within the combustion chamber while suspended in the gas flow and are not combusted at the furnace wall.
