Abstract From the Canadian patent

System for Burning Pulverised Fuel Enhanced combustion of pulverised fuel in an oxy-fuel burner (10) is achieved by replacing the conventional pulverised fuel feed with a dense phase material flow transport system. This enables materials which would hitherto have been discarded as waste to be used as a viable energy source. In addition to greatly enhancing combustion the swirlers conventionally associated with the oxy-fuel burner (10) may be omitted.
