Combustor

摘要

A nozzle for injecting fuel oil into a fluidized bed combustor has a pair of co-axial tubes, each of which is connected to an air supply and each having internal outlets. The inner co-axial tube projects beyond and has its outlet beyond the outer co-axial tube outlet. The oil is supplied from a further tube within the inner co-axial tube and having its outlet near the outlet of the inner tube. Air passing down the inner tube entrains the oil emerging from the oil supply tube and the oil/air mixture then passes into and is reacted in the fluidized bed.
