Process of preparing a fuel

Abstract From the Canadian patent

Fuel particularly useful in cyclone burners is prepared by a process in which in the first step wood is ground to a powder with a particle size of up to about 15 mm. The resultant powder is dried to a moisture content of maximum 15% (preferably maximum about 10%) and this, dried powder is ground in a second step to an average particle size of between about 100-900 µm (preferably maxi-, mum 700 µm). This fuel with an average particle size, of below 900 µm and with a moisture content of maximum 8%, can be used as fuel in steam or hot water boilers hot air boilers, internal combustion engines and the like.
