    摘要: The invention provides a pulverized fuel burner including a nozzle body 6 open to a furnace 1 to inject pulverized fuel together with primary combustion air, flow passages for secondary combustion air formed coaxially around the nozzle body and shutters arranged circumferentially along the flow passages and spaced apart from each other at specified intervals. Non-flow portions are formed by the shutters for the flow passages for the secondary combustion air to bring about backflow of hot flue gas. As a result, ignition performance can be improved with pulverized fuel containing less volatile matter and the flame can be continuously kept stably.
