BURNER STRUCTURE

摘要

A burner structure capable of more accurate air flow rate control for combustion air with a lone burner. In the burner structure of a boiler including an air passage (11) of a blast box (12) for injecting the combustion air into a furnace (1) having a bend (13) immediately before the furnace and one or more guide vanes (14) provided in the air passage (11) of the bend (13), a wind drift control dumper (16) is provided for making variable a flow path resistance ratio of each of a plurality of sections of the air passage (11) divided by the guide vanes (14).
