<p>This abstract describes a type of burner in which gaseous or liquid fuel is used to provide a high temperature environment, with excess air, into which a low heat value "lean" gas can be introduced to be burned. It comprises a cylindrical housing lined with refractory, having a closed end and an open end, adapted to be inserted into a furnace wall. Liquid fuel burner means can be inserted into the closed end and/or gaseous fuel can be introduced in a tangential rotary manner, with excess combustion air introduced through ports in the closed end of the housing. Combustion of these fuels provides a high temperature gaseous environment into which the lean gas can be introduced, in a tangential manner, downstream, so that the lean gas will be burned with the excess air provided.</p> |
